Now that the Senior Bowl is officially in the books, it is time for me to give you the first part of my 2012 NFL Draft big board. In the future you will see this list expanded, but for now I think it makes more sense to just give you the top 40.

I did take into account the performances during the Senior Bowl in coming up with these rankings. 

1. Andrew Luck, QB, Stanford

Luck is by far the No. 1 overall prospect in the 2012 NFL Draft. It's pretty much a certainty that Luck will be the Colts starting quarterback heading into the season. He does have the capability to have immediate success much like what we saw with Andy Dalton and Cam Newton this season. It is just up to the Colts to surround him with good skill position players. 

2. Trent Richardson, RB, Alabama 

I don't think I went out on a ledge by saying that Trent Richardson is the best running back prospect since Adrian Peterson. He has all the necessary skills to be a dominating player in the NFL: speed, size, strength and vision. 

3. Robert Griffin III, QB, Baylor

If Griffin III had decided to return to Baylor for his senior season, he would have been the top prospect heading into the season. Instead, he has to settle for No. 3 in 2012, not bad considering where he was this time last season. Look for the Dolphins or Redskins to trade up with the Rams for his services.

4. Morris Claiborne, CB, Louisiana State 

Claiborne is already a much better cover corner than his former teammate Patrick Peterson, who went No. 5 to the Arizona Cardinals in 2011. Morris Claiborne will be a shutdown corner in the NFL sooner rather than later. I love the way he gets in the receiver's face at the line and doesn't shy away from contact. 

5. Matt Kalil, OT, Southern California 

The former USC standout has clearly separated himself from the rest of the tackles in the 2012 NFL Draft. He will need to add some weight to that massive frame, but he already has pro ready technique. Definitely a player who will be good from the get-go. 

6. Justin Blackmon, WR, Oklahoma State 

Blackmon will struggle against press coverage early in his career, but once he gets that figured out, watch this receiver become elite. He has soft hands, gains separation on the outside and uses that frame to fend off defenders. Definitely a future No. 1 receiver. 

7. David DeCastro, G, Stanford 

The best interior line prospect of the last decade, David DeCastro is going to be dominating. He clearly attacks the line, uses that strength to ward of pass rushers and has the ability to open up gaping holes. One of the best aspects of his game is the ability to pull outside as a lead blocker in the running game. 

8. Jonathan Martin, OT, Stanford

The All-American would probably be a top tackle in most drafts, but the 2012 version is absolutely stacked. Martin is just as good in pass protection as he is in run blocking. He has protected, with a tremendous amount of success, the blind side of Andrew Luck for two seasons. That pretty much says it all. 

9. Courtney Upshaw, LB, Alabama 

Despite not having a tremendous Senior Bowl, Courtney Upshaw did show us all why he has to be considered a top-10 prospect. He can play in both the 3-4 and 4-3 scheme, which is a huge plus for his draft stock. What I like most about his game is the fact that he can drop back into coverage and man the middle of the field. Definitely going to be a dominating force in the NFL for years to come. 

10. Michael Floyd, WR, Notre Dame 

Some may disagree with my assessment of Michael Floyd in placing him in the top 10. However, you rarely see a wide receiver at this level who can come in and contribute immediately. The former Golden Domer might not have the upside of an Alshon Jeffery, but he will be a consistent 1,000-yard guy.

11. Michael Brockers, DL, Louisiana State 

With absolutely amazing strength and athleticism for a man his size, Michael Brockers is going to shoot up the draft boards following the LSU Pro Day and the NFL scouting combine. He is an absolute freak of nature, reminding me a great deal of a young Warren Sapp.

12. Devon Still, DL, Penn State

Overshadowed the the decision of the aforementioned Brockers to go pro, Devon Sill is as steady as they come. His upside might not be tremendous, but the former Penn State star is already a pro-ready defensive tackle. Expect him to get play from both 3-4 and 4-3 defenses come April. 

13. Mike Adams, OT, Ohio State 

No player helped his draft stock during the Senior Bowl than Mike Adams. He was dominating at the point of attack against "elite" competition, getting his hands into the midsection of players like Melvin Ingram and fending them off or pushing them off the line. He will be a top-15 pick if this success continues. 

14. Lamar Miller, RB, Miami (FL)

Miler is probably one of the most dynamic offensive playmakers in the entire draft. Lamar Miller has the capability to be a three-pronged back: He is solid in pass protection, runs pretty damn good routes and is an elite runner. I love his speed and the fact that he can get to that second gear before defenders have an opportunity to adjust. 

15. Whitney Mercilus, DE, Illinois

My opinion of the 2011 NCAA sack leader hasn't changed over the last few weeks. He is going to be a dynamic pass rusher at the next level. This is a dude that plays with a non-stop motor, has the ability to bull rush offensive tackle and can utilize that speed to get to the outside. 

16. Quinton Coples, DE, North Carolina

Despite struggling against the run in the Senior Bowl, Quinton Coples absolutely dominated Kelechi Osemele and other offensive linemen that he faced. Effort has been a major question in regards to the former Tar Heel, but if he gives 100 percent that will take care of itself. One of the most talented players in the entire draft. 

17. Zach Brown, LB, North Carolina 

Speed kills, just ask individuals who were asked to block Zach Brown in the open field during the Senior Bowl. He flew to the ball, made sure tackles and showed everyone that sideline to sideline speed that best defines his game. 

18. Melvin Ingram, DE/LB, South Carolina

Ingram did struggle to put pressure on the quarterback when he went up against Mike Adams, who had the bet of him. That said, his effort never lacked and he changed up pass-rush moves as the game went on. This is a huge benefit of Ingram's game, and it was not lost on the scouts watching the Senior Bowl. 

19. Stephon Gilmore, CB, South Carolina 

One of the trendy picks to be the No. 2 corner off the board, Stephon Gilmore is as good as it gets in man coverage. He uses that frame to close gaps against the receiver on the outside and has pro-ready hip technique going down field. Fully expect this to be on display as the postseason progresses and the closer we get to April. 

20. Kendall Wright, WR, Baylor

Definitely one of the better "slot" type receivers in the draft, Kendall Wright is going to be a huge downfield threat at the next level. He reminds me a great deal of DeSean Jackson in that he has the ability to stretch the field. Will need to refine his route running in order to make an immediate impact. 

21. Nick Perry, LB, Southern California 

Purely a 3-4 outside linebacker in my book, Nick Perry already has a few different pro-ready pass-rush moves. I love the way he uses his hands to keep the blockers off-balance and throw them into the offensive backfield. Will be a double-digit sack man in the NFL. 

22. Bobby Wagner, LB, Utah State 

The fastest riser of any player on my big board, Bobby Wagner showed scouts during the Senior Bowl what most of us have seen on tape. He is an elite backer with the ability to cover running backs and tight ends between the hashes. Reminds me a great deal of All-Pro linebacker NaVorro Bowman. 

23. Mark Barron, S, Alabama 

Markelle Martin might have closed the gap during Senior Bowl week, but Mark Barron is still my top safety on the board. He can enter the box against the run and drop back to cover over the top. A two-pronged safety in the mold of Ed Reed. 

24. Vinny Curry, DE/LB, Marshall 

The two sacks that Curry acquired during the Senior Bowl don't tell the entire story. He is going to be an absolute beast at the next level. He isn't a player who will utilize just one pass-rush move. Instead, Curry has a wide array of different moves that should scare the hell out of opposing offenses. Looks to be a better fit as an outside backer in a 3-4. 

25. Jamell Fleming, CB, Oklahoma 

Fleming quickly overtook the likes of Janoris Jenkins and Alfonzo Dennard with his play during Senior Bowl practice. This was only magnified by a tremendous performance in the actual game: an interception and forced fumble. Has a chance to jump even higher as the postseason events continue. 

26. Alfonzo Dennard, CB, Nebraska 

Dennard really struggled in coverage throughout practice this week and didn't show up well when it counted the most with scouts on hand. Some have even suggested that the former Nebraska standout translates better as a safety. One of the biggest drops on my big board, from No. 8 to 26. 

27. Dre Kirkpatrick, CB, Alabama 

It isn't just that Kirkpatrick made a boneheaded mistake off the field following his declaration for the draft. The talented corner struggled a great deal in 2011 with technique, showing extremely stiff hips. If he doesn't improve this postseason, you could see Kirkpatrick fall completely out of the first round. 

28. Cordy Glenn, G, Georgia 

I didn't really notice Glenn in the Senior Bowl, which is probably a good thing considering he is an offensive linemen. He did get called for a false start and had a blatant hold that wasn't called. Translates much better as a guard than a tackle moving forward. 

29. Janoris Jenkins, CB, North Alabama 

Jenkins really struggled in coverage during the Senior Bowl. A lot of this had to do with the rules that disabled his ability to play press, which is a strength. Make no mistake about it, Jenkins is still a first-round talent. Will also have to interview well to put behind those character concerns that have come to define him.

30. Doug Martin, RB, Boise State

He showed great vision in the Senior Bowl and fully understood the need to run behind blockers between the hashes. Martin picked up some solid blocks in the offensive backfield and ran a couple nice routes as well. Look for Martin to get some play late in the first round if this success continues. 

31. Alshon Jeffery, WR, South Carolina

I am definitely not as high on Jeffery as others. I think that he will struggle early on to refine that route-running ability and gain separation downfield. Definitely a high risk, high reward player. Best case scenario would be Hakeem Nicks, worst case scenario would be Roy Williams. 

32. Luke Kuechly, LB, Boston College

His inability to get into the offensive backfield wasn't a big deal for me prior to seeing some of the other backers play during the Senior Bowl. Comparing Kuechly to a player like Dont'a Hightower and Bobby Wagner really doesn't make this B.C. product look too good. 

33. Dont'a Hightower, LB, Alabama

Make no mistake about it, the former Alabama stud is only this low on the list due to a wide array of injury concerns. If Hightower proves he can stay healthy, he will be a top-20 pick. 

34. Dwayne Allen, TE, Clemson 

A lot of people have put Orson Charles No. 1 on their tight end ranking list, but not me. I am extremely fascinated with the skills that Dwayne Allen provides. He is a major threat between the hashes against smaller linebacker and safeties. The former Clemson star also has really good hands.

35. Vontaze Burfict, LB, Arizona State

This ranking will probably change a great deal following Arizona State's Pro Day and the NFL scouting combine. However, the game film that I watch in regards to Burfict really doesn't impress me too much. He will struggle in coverage and takes himself out of a lot of plays due to over-pursuing on the outside. 

36. Chris Polk, RB, Washington 

Polk fell out of the top 20 due to a lackluster Senior Bowl performance. He didn't show much patience and wasn't nearly as fast as most of us expected. He struggled getting to the outside and didn't show great field vision. The talent is there, however, he just needs to show it more consistently. 

37. Mohamed Sanu, WR, Rutgers

Sanu really has a chance to make his mark in the slot for a team that is missing that type of threat. He utilizes that frame to fend off receivers, catches nearly everything thrown his way and can gain separation down field. A real wild card. 

38. Alameda Ta'amu, NT, Washington

His performance in the Senior Bowl might fly under the radar, but this net tackle just surpassed Dontari Poe as the best in the draft. He continually dominated the line, throwing opposing offensive linemen into the offensive backfield. Ta'amu is going to be a great run-stuffing, 3-4 net tackle. 

39. Nick Foles, QB, Arizona

Foles really separated himself from the rest of the second-tier quarterbacks in the Senior Bowl. He showed excellent field awareness, stepped into a majority of his throws and put the ball on target consistently. Has a chance to slip into the first round if this performance continues. 

40. Markelle Martin, S, Oklahoma State

Because of the rules in coverage during the Senior Bowl, Markelle Martin had a chance to show scouts that coverage wasn't his weakest link. Well, he did very good in regards to that. He stayed with tight ends, causing quarterbacks to go past their primary read. This is going to help good pass-rushing teams moving forward in the NFL. Definitely cemented his status as a second round pick.
