Jonathan Cooper is one of the few interior linemen that could go in the first round.
There are still regional combines, the NFL Combine, and pro days to go, as well as the free agency period for NFL teams, but we will look forward and speculate nonetheless.
As of now, the Colts have multiple offseason needs, which need to be addressed partially through the draft. Those needs include offensive and defensive line, outside linebacker, wide receiver, cornerback, and safety.
Which will they address via the draft?
Trufant (6) had an outstanding Senior Bowl week, which has shot him into the first round.
CB Desmond Trufant, Washington
The Colts need a starting cornerback, and corner is one of the thinner positions in free agency this offseason. Chances are the Colts will exit free agency with a lot of holes in their secondary, and need to look for big-time talent to help fill those holes.
Trufant may be that talent. He has the size and length to be a very good press man corner, but also has experience and skill to be able to disguise and run other coverages as well. He's shown great hips and fluidity over the past year, and can cover just about anybody. He had a very strong senior season, and looks to be a late first rounder.
If the Colts could trade down a few slots and still pick up Trufant, that would be ideal, but that may not be possible, especially if he measures out well at the combine.
Porter quickly earned Von Miller comparisons while at Texas A&M.
LB/DE Sean Porter (Texas A&M)
Unless the Colts pick up a guy like Anthony Spencer in free agency, outside linebacker is going to be a huge liability in 2013. Porter is one guy in the third round that could prove to be a steal.
Porter has drawn comparisons to Von Miller from just about everybody, a dangerous edge rusher who also is strong against the run. The Colts run defense struggled just as much as the pass rush this season, largely because of failures to seal the edge. Porter would certainly help in that regard, and his ability to drop back in coverage sets him apart when it comes to OLB prospects.
Hugh Thornton is a big, nasty guard that would instantly upgrade the Colts' run offense.
G Hugh Thornton, Illinois
The Colts' biggest hole on offense is offensive line, and the mid-late rounds could be a perfect place to get some depth and potential for the interior.
Thornton could be a potential starter at guard, a mauler who gets great initial contact as a downhill blocker. He also has the athleticism to pull if need be, and has above-average awareness for the position.
Thornton has been projected to struggle in pass protection on the next level, with technique that does not stand out, and feet that may not be quick enough to stay with quicker defensive linemen.
Mellette's a small-school wide receiver who may be overlooked in the draft.
WR Aaron Mellette, Elon
Mellette is a small-school receiver who had very consistent production over his career at Elon. Unfortunately, Mellette looked much worse against higher levels of competition, and it showed during Senior Bowl week. Mellette's poor week has seen him drop in many mocks, and he could slip into the late sixth round very easily.
On the positive side, Mellette has great size (6'4", 212 pounds) and the quickness to be a possession receiver at the next level. The Colts need a big target who can get them some consistent production. If Mellette works out, it's exactly what he would be.
