Ah yes, Indianapolis, home of mid-west BBQ, the Indy 500 and of course, Lucas Oil Stadium, the birthplace of the NFL combine. This is where all 32 teams come out for a week during the offseason and watch as over 300 prospects try to prove to everyone that they are worthy of being one of the 257 picks called in Chicago on the week of April 28.

There are multiple prospects who are for sure top-level talent, and will hear their names called early by an NFL franchise. However, there are several players, both top level and bottom tier, who must prove they are worth their draft grade, and a pick for a team. Sure, while some positions will be chosen due to age or lack of talent, a great day in Indy can be the difference between a one and a million chance to play in the NFL or a multi-million dollar contract.

With that in mind, here are the top 10 players or groups that must perform well in Indianapolis to hear their name called by commissioner Goodell in the upcoming months.

Any Quarterback Not Named Jared Goff

While many people (Including myself), are sold on Carson Wentz, multiple scouts agree that Cal’s quarterback prospect, Jared Goff, is the only solidified first-round quarterback prospect in this year’s draft class. Both Wentz and Paxton Lynch have the size, talent and arm strength to be first-round draft picks, however, they must prove that their small school or one-year-wonder phase isn’t going to be a problem at the next level.

Also, quarterback prospects such as Michigan State’s Connor Cook, Penn State’s Christan Hackenberg and Mississippi State’s Dak Prescott all can be legitimate day-two pickups, and can compete with quarterbacks who are on the bubble for starting teams. Six rookie quarterbacks could find themselves leading an offense sometime next season. The question is: are they ready to take on that type of responsibility?

Sterling Shepard, WR, Oklahoma

One of the top slot receivers in this year’s class, Sterling Shepherd is almost a for sure lock to hear his name called sometime during the draft in April. While his fundamentals to be a NFL receiver are in place, speed is what he lacks, which will push him down the list. Averaging a 4.63 40 time, Shepard must burn off some of his time in order to prove he can be a solid receiver in the NFL. Sitting around the 3-5 round range, Shepard could easily solidify himself a day-two prospect with his sure hands and his new-found speed with a good day in Indianapolis.

Jihad Ward, DE, Illinois

While the Fighting Illini isn't the most popular school for football, they have produced several defensive gems over the years such as Ras-I-Dowling and Whiney Mercilus. Jihad Ward, their strong-side defensive end could be the next on the list with his explosion from the ground, and his ability to reach the quarterback in a matter of seconds.

Ward thrived in Mobile, Alabama, but didn’t put up the proper numbers during the 2015 season to lock up a first or early second-round grade. Ward has to prove that it wasn’t just a “one hit wonder” in Mobile during his time in Indy. If he can prove it wasn’t just a fluke, Ward could find his way into an early day-two selection.

Shaq Lawson, DE, Clemson

Shaq Lawson on my board is a top 10 selection due to his ability to reach the quarterback from both a three-and-five point stance. However, many scouts believe that Lawson’s lack of speed off the edge could cost him a full round and he could possibly become the next Randy Gregory.

Gregory not only got in trouble just days before the draft, but he also had a terrible combine in front of the scouts. Lawson has to show scouts he can be flexible off the edge and keep a low body frame in order to stay a top 15 pick in this year's class.

LaQuon Treadwell, WR, Ole Miss

It might be shocking to see many people's consensus top wide receiver on my list, but many do believe that the Ole Miss product could be slipping fast. According to Bleacher Report’s Matt Miller, teams are worried that Treadwell’s speed will cost him several spots in this year’s draft. While Treadwell should still be a first-round pick, he must prove that his hands will save him as a top 15 grade. Either way, Treadwell’s speed shouldn't hurt him that much, but it still might be an issue in the long run.

Both Jaylon Smith and Myles Jack, LBs, UCLA & Notre Dame

Another pair of top-25 picks, Notre Dame’s Jaylon Smith and Myles Jack both won’t be able to fully compete at the combine. While their numbers throughout college are impressive, tearing an ACL could cost them not only a top-five pick but possibly a first-round grade.

Jack, who is further along than Smith in his rehab, needs to prove his versatility at both the outside and inside linebacker positions. Smith, who will mostly be performing in the linebacking group, must show he can work in both coverage and in a quick toss to the outside. Either way, while scouts may have top-level grades for the pair of linebackers, they must prove their grade in Indy.

Josh Doctson, WR, TCU

Josh Doctson is one of the few strange prospects in this year’s draft class. Being compared to everything from AJ Jenkins to the next Odell Beckham Jr., Doctson is more known as a possession receiver. The former Wyoming wideout put up huge numbers during his senior campaign while showing he’s very skilled in the vertical route running.

Undersized for a tall receiver, Doctson must prove he can get off top-level corner blocks and find a way open for quarterbacks to hit him with the deep ball. There are multiple receivers with higher draft grades than Doctson, however, he might have the most upside after a successful day in Indy.

Devontae Booker, RB, Utah

A consensus top-five running back before tearing his meniscus, Devontae Booker proved that he could be a three-down back in the NFL. Tearing a meniscus is an awkward injury to come back from, and usually, players who do tear it don’t have long careers in the NFL due to the wear and tear on their body.

A patient runner who makes quick decisions and usually gains a safe amount of yards, Booker could find his way into the same role as former Michigan State’s running back Jeremy Langford found himself a year ago. While he doesn’t have top speed, Booker has to prove he can be a solid secondary back and could be strong in the blocking game, so an NFL team will take a risk on him even though he’s fighting an injury.

Kendall Fuller, CB, Virginia Tech

Yes, while injury-plagued players do get a bit of an edge over any player, Kendall Fuller is the one player on this list who was a for sure former first-round player that slipped out because of injury. While he missed most of his junior season, Fuller has first-round talent like his brother, Kyle, and could find his way back into a first- round grade.

Great direction to the ball and a “ball hawk” with eight interceptions in 2014, Fuller has to show scouts that he still has the top speed before going under the knife to repair muscles in his knee. Fuller could go as high as pick 21 to the Redskins however, if his combine turns out to be a terrible day, he could become the next Ifo Ekpre-Olomu and see his draft stock plummet to the end of day three.

Any Safety Prospect

As someone who believes that the draft is a smarter way to find immediate needs, the safety prospects in this year’s class seem to be weaker than in recent years. So far no safety has anything higher than a mid-second round draft (even on my board), due to the lack of playing time as well as significant numbers. While Florida State’s Jalen Ramsey is expected to move from cornerback to free safety at the next level, he doesn't count until the team announces their plan for him.

Duke’s Jeremy Cash, Boise State’s. Darian Thompson and Ohio State's Von Bell all could boost their second and third round grade to a late first round with excellent numbers at the combine. Several teams towards the end of the first round are looking for a safety to lead their defense. However, just because it’s an immediate need, that doesn’t mean a team will jump the gun early on a player without the proper numbers.
