The NFL Scouting Combine can be the greatest of friends to some prospects.
It can also be the greatest of enemies.
Sometimes it's better for prospects to not participate in certain drills in the combine for their own sake. A few prospects are probably wishing they could go back in time after Monday's showings in Indianapolis.
Here's a look at prospects whose draft stock dropped on Monday at the 2013 NFL Scouting Combine.
Manti Te'o, ILB, Notre Dame
Te'o officially ran the 40-yard dash in 4.82 seconds on Monday, which didn't even make it onto the first page of times on NFL.com.
Of course, the 40-yard dash isn't the ultimate indicator of how a player will move around on the football field, but given Te'o's lackluster performance against Alabama in the BCS National Championship Game—as well as previous concerns about his sideline-to-sideline ability—Te'o's 40-yard time was magnified on Monday.
There was also the priceless reaction by Baltimore Ravens head coach John Harbaugh, per NFL.com. That reaction was especially bad considering the Ravens were one team that could have targeted Te'o in the first round on draft day.
Damontre Moore, DE, Texas A&M
There were already scouts and draft analysts remarking that Damontre Moore's athleticism and explosiveness were overrated headed into the combine.
That view of the 6'4", 250-pounder appeared to be backed up on Monday when Moore failed to impress on the bench press and in the 40-yard dash.
Moore officially recorded 12 reps at 225 pounds on the bench press on Monday. That was the lowest mark of any linebacker or defensive lineman. He also ran the 40-yard dash in 4.95 seconds.
Moore's time in the 40 could improve at his March 8 pro day, given he tweaked his hamstring during the event, but his mark in the bench press was simply stunning...in a bad way.
NFL Network analyst Mike Mayock was particularly harsh.
Mayock said, via NFL.com:
I wasn't high on Damontre Moore. I hear top five, I don't believe it. And by the way, he did (12) reps at (225 pounds). That is totally unacceptable. I don't know how you convert speed to power if at 250 pounds you can only bench press 225 11 times. So I'm kind of poking holes in all these supposed top 10 guys because I'm not seeing it.
Jesse Williams, DT, Alabama
Who hurt their draft stock the most on Monday?
Alabama nose tackle Jesse Williams didn't post one of the worst marks on the bench press on Monday, but he didn't post one of the best, either.
Williams posted 30 reps on the bench press. Twelve other defensive lineman/linebackers equaled his mark or surpassed it.
Why is that particularly significant?
Williams' showing on Monday prompted some needling from Ian Rapoport of NFL.com:
The 6'3", 323-pounder is still a strong guy, but perhaps his strength was a bit exaggerated.
