Indianapolis Colts Mock Draft: Updated Day 3 Predictions

The Indianapolis Colts have been busy during the first two days of the 2015 NFL draft, but with the final day of selections approaching, the team still has more than a few picks to deal with on Saturday.

It was a bit of a surprise to see the Colts take a wide receiver in the first round, but fans should be excited about the explosive Miami prospect in Phillip Dorsett. After the initial shock of a first-round receiver died off, Colts fans watched the team address the defense in the third round, bringing in D'Juon Smith at cornerback and Henry Anderson at defensive end.

The Colts traded back a few spots with the Tampa Bay Buccaneers to move out of the second round, but in return, the two teams swapped fourth-round selections. That means that the Colts will be drafting 19 spots earlier in the round, giving them some better options to work with.

Saturday is bound to be filled with plenty of interesting prospects, but there could also be some more trades in store for the Colts. However, before any more trades happen, let's take a look at one last mock draft for Day 3, looking at some potential options for the Colts.

Round 4

Pick No. 109: Derron Smith, S, Fresno State

Moving up 19 spots in the fourth round could finally give the Colts an opportunity to address the safety position. While they could use a strong safety to play alongside Mike Adams, at this point they'll take whatever safety that they can get.

Through Friday, Derron Smith from Fresno State is arguably the most talented safety still available. While only 5'10'' and 200 pounds, Smith has the experience as a four-year starter at Fresno State and plays with the aggressiveness scouts love at the position.

Smith can play either in the box or back in coverage. He's a fearless prospect who's not afraid to make big hits, but he's an even better player in coverage thanks to his instincts and ball skills. He'll have trouble covering bigger tight ends at the next level, but he can still cover most receivers or run downhill and help stop the run.

Overall, Smith looks like a nice prospect who could complement Adams well. He probably translates best as a free safety, but the Colts can worry about that once Adams decides to retire.

Pick No. 165: Hayes Pullard, ILB, USC

With the safety position addressed in the fourth round, the Colts can go back to looking for more help in their defensive front seven. While fifth-round prospects probably aren't going to come in and be instant starters, they should at least be able to come in and be productive rotational guys.

That sounds like the ideal role for a player like USC's Hayes Pullard. He has some nice size at 6'0'' and 240 pounds but is also an impressive athlete. Pullard does a good job of making plays in open space and preventing running backs from finding cutback lanes. In pass coverage, he's quick enough and has the ball skills to be an asset in the NFL.

Pullard's instincts aren't the greatest, however, and that hurts his stock. He isn't the best linebacker in traffic and doesn't do the best job of disengaging from blockers. However, because of his athleticism, aggressiveness and ability to drop back in coverage, Pullard makes a lot of sense in Indianapolis.

Round 6

Pick No. 205: Ibraheim Campbell, SS, Northwestern

There is such a severe lack of depth at the safety position for the Colts that I think they seriously need to consider drafting two players at the position despite a thin safety class.

Ibraheim Campbell would be a nice addition in the sixth round if he's still available. He is an aggressive safety with a decent frame at 5'11'' and 208 pounds. He finishes through tackles and is able to force some turnovers by stripping ball-carriers. 

Although there is still a lot of work for Campbell in pass coverage, his instincts and athleticism make him a nice option to look at for a potential strong safety.

Pick No. 207: Dillon Day, C, Mississippi State

Jonotthan Harrison and Khaled Holmes will be fighting for the starting center spot in 2015, but there still needs to be some more depth at the position and on the offensive line in general.

After starting four years at Mississippi State, Dillon Day has earned a shot to play center in the NFL. He's a smart player who recognizes defenses and makes the right adjustments. However, he isn't the biggest prospect and isn't athletic enough to take on some of the more physically gifted defensive players at the next level.

Day has a limited ceiling because of his physical traits, but his experience and toughness should give him the opportunity to prove himself in training camp.

Round 7

Pick No. 244: Trey Williams, RB, Texas A&M

I have a feeling that the Colts might try to draft a running back before the seventh round, but if they don't, someone like Trey Williams would be an interesting player to play behind Frank Gore.

Williams is one of the smaller prospects in this draft at just 5'7'' and 195 pounds, but he's a terrific athlete with explosiveness at the line of scrimmage to help pick up yards in bunches. He's a shifty runner who can make defenders miss, but also has the skills to be an effective pass-catcher out of the backfield.

A lack of size and concerns about his role as a pass protector mean that there's no guarantee he'll be drafted on Saturday, but if the Colts take a chance on him, I could see them using him in the same role they used Ahmad Bradshaw last season.

Pick No. 255: Ryan Russell, DE/OLB, Purdue

I will continue mocking the Colts to take Ryan Russell just because I believe in his potential, and the fact that he played at Purdue will make some fans happy to see him get a chance at the roster.

Russell has all the physical traits you want in a pass-rusher at 6'4'' and 269 pounds, but he never had the production scouts wanted to see while playing with the Boilermakers. He's a raw pass-rusher who has a lot to work on, but he could be an interesting project for the Colts to have on the practice squad once the regular season begins.
