NFL Draft 2015: 1st-Round Mock Draft Predictions for Each Team

The NFL draft is pretty set at the very top. Most experts believe that the Tampa Bay Buccaneers will take Jameis Winston No. 1 overall, if not Marcus Mariota. 

There seems to be a lot of room for wheeling and dealing just about everywhere else on the board. Here's the way I believe the first round will shake out:

Pick	Team	Selection
1	Tampa Bay Buccaneers	Jameis Winston, QB, Florida State
2	Tennessee Titans	Leonard Williams, DE, USC
3	Jacksonville Jaguars	Dante Fowler Jr., DE, Florida
4	Oakland Raiders	Amari Cooper, WR, Alabama
5	Washington Redskins	Vic Beasley, LB, Clemson
6	New York Jets	Marcus Mariota, QB, Oregon
7	Chicago Bears	Shane Ray, LB, Missouri
8	Atlanta Falcons	Randy Gregory, LB, Nebraska
9	New York Giants	Andrus Peat, OT, Stanford
10	St. Louis Rams	Kevin White, WR, West Virginia
11	Minnesota Vikings	Trae Waynes, CB, Michigan State
12	Cleveland Browns	Danny Shelton, DT, Washington
13	New Orleans Saints	DeVante Parker, WR, Louisville
14	Miami Dolphins	Jaelen Strong, WR, Arizona State
15	San Francisco 49ers	Malcom Brown, DT, Texas
16	Houston Texans	La'El Collins, T, LSU
17	San Diego Chargers	Todd Gurley, RB, Georgia
18	Kansas City Chiefs	Brandon Scherff, OT, Iowa
19	Cleveland Browns	Ereck Flowers, OT, Miami (Fla.)
20	Philadelphia Eagles	Landon Collins, S, Alabama
21	Cincinnati Bengals	Eli Harold, LB, Virginia
22	Pittsburgh Steelers	Jalen Collins, CB, LSU
23	Detroit Lions	Eddie Goldman, DT, Florida State
24	Arizona Cardinals	Melvin Gordon, RB, Wisconsin
25	North Carolina Panthers	Arik Armstead, DE, Oregon
26	Baltimore Ravens	Dorial Green-Beckham, WR, Oklahoma
27	Dallas Cowboys	Kevin Johnson, CB, Wake Forest
28	Denver Broncos	T.J. Clemmings, OT, Pittsburgh
29	Indianapolis Colts	Cedric Ogbuehi, OT, Texas A&M
30	Green Bay Packers	Marcus Peters, CB, Washington
31	Seattle Seahawks	Breshad Perriman, WR, UCF
32	New England Patriots	Jordan Phillips, DT, Oklahoma

Caught in a Haze

Randy Gregory, an outside linebacker out of Nebraska and, by all acclamation, a top-10 talent, recently admitted that he tested positive for marijuana at the scouting combine in February.

There is speculation about whether teams will be scared away from selecting Gregory and just how far he might fall in the draft. 

Gregory told NFL.com that the first time he smoked marijuana was after he graduated from high school and that he "failed to qualify academically at Purdue, which represented a considerable disappointment to him, and Gregory said he turned to marijuana to cope with the anxiety."

There is precedent for big-name draft prospects plummeting in the draft after a failed drug test during the combine.

Justin Houston was expected to be a first-round pick out of Georgia, but he fell all the way to the third round where the Kansas City Chiefs selected him 70th overall, according to Seth Emerson of the Ledger-Enquirer.

Warren Sapp had been projected to go as high as the first or second overall pick in the 1995 draft, according to Dave Caldwell of The Philadelphia Inquirer. But the Hall of Famer slid all the way down to the 12th selection by Tampa Bay due to reports of failed tests, Caldwell wrote.

Getting drafted later didn't damage Sapp's career and, so far, it isn't hurting Houston's. Last year, Houston came within half a sack of breaking Michael Strahan's single-season record of 22.5.

The NFL draft has always been a gamble and because he has similar tools, the 6-foot-5 Gregory will make at least one NFL team want to push all its chips to the center of the table.

A failed drug test might not play as much of a role in Gregory's career in the long run—but it will likely wind up costing him upfront, ESPN's Darren Rovell said:

Prediction: Will fall out of the top five and down into the top 10.

Collins' Safety Net

Landon Collins, the All-American from Alabama, is projected as the only safety to be taken in the first round. His versatility is by far his most attractive quality, as he can play both safety positions and special teams.

If you're unfamiliar with his work, check him out here:

What's not included in the highlight package is when Collins got burned twice by Mississippi last season, causing Alabama to lose that game. The Crimson Tide led 17-10 before Collins was beaten for two late touchdown passes.

And that's the biggest concern about him. The 6-foot, 228-pound Collins is solid against the run, but experts question whether his pass defense is ready for the NFL.

ESPN NFL draft analyst Mel Kiper assessed Collins as a "system safety, and he's an in-the-box guy," according to Matt Zenitz of Alabama.com.

Prediction: Collins will be a top-20 selection.

Amari Cooper

Amari Cooper starred at Alabama, where he was a Heisman finalist and led the nation in receptions (124) and was second in yards (1,727) and touchdowns (16). Still, the debate rages on over whether he or Kevin White out of West Virginia is the top-rated wide receiver.

But, not in the mind of Fallon Smith, who covers the Raiders for Comcast SportsNet in the Bay Area:

Cooper's precise route running, big-play making ability and penchant for getting open outside the numbers as well as in the middle of the field are why Oakland will probably select him with the fourth-overall pick.

Prediction: Cooper will go fourth overall to the Raiders.
