INDIANAPOLIS -- We've already discu sed top prospects will be asked during interviews at the NFL , but what impact could on-field results at the combine have on some of this year's top talents?Here's a look at five prospects and how their performance in a certain drill, or drills, could help or hurt their stock this weekend in Indianapolis., DT, Domingo Santana Jersey TexasCombine workout day: SundayDrill: Any that show power and short-area quickne sThe skinny: Brown is ascending on colleague Daniel Jeremiah's , and colleague Mike Mayock had earlier this week. I was very impre sed with Brown's 2014 season and have watched him play live a couple of times. He can cement his status as a riser at the combine with good showings in the 10-yard split in his 40-yard dash and in the broad jump, among other drills. With Brown, , and among the top interior defensive linemen -- other than -- in this year's draft, Brown can distinguish himself from the pack by showing he can get up the field the quickest. Teams will want to see his upper-body strength (bench pre s) and lower-body power and explosivene s (broad jump)., EDGE, NebraskaCombine workout day: SundayDrill: VerticalThe skinny: Gregory is looking to emerge as the consensus top edge player in this year's draft, and he has some tough Milwaukee Brewers Blank Jersey competition in , and . He can help himself in that effort by showing off the leg drive that a lot of great pa s rushers po se s, but he'll hurt himself if he doesn't show that explosivene s and twitch that teams are looking for. had the top vertical last season with 42 inches, which is off the charts. If Gregory can hit the mid-to-high 30s, he'll be showing that athleticism that has made him one of the top-rated players available this year., QB, UCLACombine workout day: SaturdayDrill: ThrowingThe skinny: We know and are the consensus top two quarterbacks in this draft, but who's No. 3? Hundley is the pick for some people, but he can cement his status by showing off his arm and athleticism at the combine. The dynamic in throwing drills will be a little different this year, with the top quarterbacks announcing they intend to throw in Indianapolis. Quarterbacks can open eyes with how they perform in throwing drills at the combine. Hundley Mike Moustakas Jersey pa sed on a chance to compete in the -- and I'm not knocking him for that decision -- so this will be his first chance to make an impre sion on teams this draft season and show that it should be him, not , or anyone else, that should be the third QB off the board. Hundley certainly looks the part, and teams will want to see just how live his arm Burch Smith Jersey can be., ILB, Mi si sippi StateCombine workout day: SundayDrill: Agility/3-cone/shuttleThe skinny: McKinney is moving down on colleague Daniel Jeremiah's , and he could go a long way toward helping his stock by showing well when his movement skills are put to the test. He's competing against the likes of Miami's and TCU's to be the top inside 'backer off the board, and teams want to know if McKinney, the biggest of the three at 6-foot-5, 249 pounds, can play all three downs at the Keston Hiura Jersey next level. Any drill that shows his fluidity, change of direction and speed will be huge for him., WR, West VirginiaCombine workout day: SaturdayDrill: 40-yard dashThe skinny: I'm in agreement with those that rate White as the draft's top wide receiver, but I think people are still wondering about White's straight-line speed. If he runs faster than 4.5 in the 40, that would be a huge deal for him. It would distinguish him from the other top guys at his position and could be a tiebreaker in his favor for those still on the fence about who's No. 1.Follow Charles Davis on Twitter *.*
