Which players hurt their standing by their performance at this year's NFL Combine?

Ken Zalis and Matt Zenitz each picked the players who hurt their NFL Draft prospects the most with their performance at this year's NFL Combine. They both picked Mike Adams and Vontaze Burfict, and Zalis also singled out Kendall Wright.

Plus, check out their picks of the players who helped themselves the most with their performances.

OT Mike Adams, Ohio State

Ken Zalis: Slow, unathletic and weak are not the ways you want to be described if you are an offensive tackle prospect, but after the combine, that is exactly how many will describe Mike Adams. A 19 on the bench-press drill was a huge disappointment, but even more disappointing was his apparent lack of mobility in his position drills. Slow feet, no burst and not strong mean no first-round love for Adams.

Matt Zenitz: A fringe first-round prospect heading into the combine, Adams will likely fall out of the first round based on his performance during the weekend. The 6-foot-7, 323-pounder was decent during drills, but was disappointing during workouts, pumping out just 19 reps of 225 pounds on the bench press, among the worst for an offensive lineman, and running just a 5.40 in the 40-yard dash. For a player who was inconsistent during his college career and has had some off-the-field issues as well, that kind of performance won't help Adams' draft stock.

LB Vontaze Burfict, Arizona State

KZ: Burfict ran a slow (and that's being kind!) 5.09 in the 40-yard dash and had a 8 foot, 8 inch broad jump, both near the bottom for linebackers. He lacked speed, quickness and athleticism. Plus his incoming character issues and bad-guy image will force Burfict to fall to a late-round selection, if he's drafted at all.

MZ: Once viewed as a potential top 15 pick, Burfict has been on a steady decline since the start of the 2011 season. He has a ton of talent and has the potential to be a difference-maker in the NFL, but he is an immature, inconsistent player with a questionable work ethic and some serious red flags. Factor in that he appeared almost unprepared for the combine, and ended up running the slowest time among linebackers (5.09), and it appears safe to say Burfict's stock will continue to fall during the final two months leading up to the draft. After his performance Monday, it really wouldn't surprise me at all to see Burfict slide all the way to the middle and possibly even the latter portion of the draft.

WR Kendall Wright, Baylor

KZ: Kendall Wright ran a 4.6, and even worse, his 10-yard splits were slower. Wright, who many had projected as a first-round pick, is now falling. His biggest asset was speed, and he didn't show enough of it at the combine. He and Rutgers WR Mohamed Sanu, who ran even slower, could also have seen their value hurt even more as Stephen Hill and Malcom Floyd lit up the combine. Wright, who many were comparing to DeSean Jackson of the Eagles, will get another opportunity at his Pro Day, but right now, the arrow is definitely pointing down.
