The Indianapolos Colts were among the most surprising teams in the National Football League this past season. Behind the leadership of rookie quarterback Andrew Luck and a whole host of youngsters on offense, Indianapolis made the postseason afer a one-year hiatus. 

This doesn't mean that they don't have holes on the roster. In fact, they over achieved a great deal this past season. In order to continue building its young roster, Indianapolis will have to make the most of the limited number of picks it has in the upcoming draft. 

Here is eDraft's full seven-round mock draft for the Colts. 

First Round:    Jarvis Jones, Linebacker, Georgia

Even after attempting to address the outside linebacker position by signing Erik Walden, Indianapolis will need to find itself a true pass-rush specialist opposite Robert Mathis in its relatively new 3-4 scheme. Jerry Hughes just hasn't gotten it done after being selected in the first round of the 2010 draft. He has just five sacks in 40 career games. 

Jones was considered a top-10 prospect prior to lingering concerns over his neck and a lackluster postseason performance. While I don't put a lot of stock in slow 40 times for defensive players, Jones' lackluster performance in that category (4.90 seconds according to Mike Mayock) really does leave me a bit concerned. This is why I have him dropping all the way to the 20's. In terms of production, you can't get better value here. Jones led the SEC in sacks in each of the last two seasons and would help improve the Colts' pedestrian pass rush. 

Third Round:    Tharold Simon, Cornerback, Louisiana State 

After yielding their second-round pick to the Miami Dolphins for Vontae Davis, the Colts attempt to fortify what was a weakness last season. While Simon hasn't received a great deal of play leading up to the draft, he has been a darn good defender for LSU over the last two seasons. He recorded a total of 24 passes defended during that span, which is a representation of just how good he is as an on-the-ball cornerback. Again, this is something that the Colts desperately need. 

Simon already possesses pro-ready technique and fluid hip movement on the outside. This means that he shouldn't have much of an issue transitioning to the NFL. This pick enables the Colts to find an immediate upgrade in the slot with a future projection for Simon as an outside force next to Davis. 

Fourth Round:   A.J. Klein, Linebacker, Iowa State

While the Colts do seem to have somewhat of an underrated linebacker group with Kavell Conner and Jerrell Freeman, neither are going to be above-average starters moving forward. In fact, both are complementary players at best. Klein may not translate into being much more than that, but he has tremendous upside and is a soldi tackler between the hashes. 

Sixth Round:    Chris Jones, Defensive Line, Bowling Green

One of the most underrated defensive line prospects in the entire draft, Jones could be a real steal here. He fits perfectly into the Colts 3-4 scheme and can play both inside and outside. Equally as important, Jones is stout against the run. While he is a bit of a project, the upside is definitely here. 

Seventh Round:  Ray Graham, Running Back, Pittsburgh

Even with Vick Ballard jumping on to the scene last year as a rookie, Indianapolis needs to find more depth and talent at running back. Former first-round pick Donald Brown averaged less than four yards per rush last season and has missed time in three of his first four NFL seasons. In short, he can't be counted on. Coming off a productive career at Pittsburgh, Graham could be that third-down back that I am sure the Colts are looking for. 

Seventh Round:   Cooper Taylor, Safety, Richmond

Taylor was a starter at Georgia Tech before transferring to Richmond. He hasn't been on the radar of the mainstream scouting community since leaving Atlanta. A lot of this has to do with the fact that Taylor was diagnosed with Wolff-Parkinson-White Syndrome during his sophomore campaign. He has had corrective procedures done since and was cleared to play following his transer to Richmond. 

He translates more as an in-the-box strong safety, but does possess the necessary skill to be decent in coverage over the top. Considering that this is the final selection in the 2013 NFL draft, Indianapolis will be looking for someone that can produce on special teams and sit on the practice squad. In terms of projection, Taylor has a pretty high ceiling for such a low-level prospect.
