It's a different year this time around. Most of the guys on this list would already be signed to a team -- albeit with brief contracts -- and ready to work toward a future in the NFL.
But this year, if you're not already aware, NFL teams had to turn out the lights after the draft reached its completion on Saturday evening. Players drafted can't have contact with their new teams, and teams aren't allowed to make offseason moves.
That means no signing of undrafted rookies, creating uncertain futures for these guys. Undrafted guys have plenty of value -- for example, last year's leading rusher among rookies, LeGarrette Blount of Oregon, went undrafted -- and here are a few guys looking for their shot in the future once the lockout ends. (It'll end eventually, right?)
Here are the Big 12 players that were productive in college and would be in camps, but thanks to the lockout, now have their futures on hold.
Tim Barnes, C, Missouri
Barnes was the first-team All-Big 12 center in 2010, but extended a streak of four consecutive Missouri centers to earn that honor and go undrafted. Barnes had more athleticism than his predecessors, but it wasn't enough to get drafted. You won't find a much more knowledgeable center, but a lot of that knowledge might not transfer well to the next level.
Kevin Rutland, CB, Missouri
Rutland was one of the Tigers' team captains last season, but his overall position skills weren't on the level of the cornerbacks drafted ahead of him.
David Sims, S, Iowa State
Sims has great speed at 204 pounds, but his 5-foot-9 frame isn't ideal for a safety. His past didn't help him, either. He enrolled at Oklahoma originally, but didn't qualify and went to junior college. After winning Big 12 Newcomer of the Year in 2009, he was suspended for the season opener in 2010 and stripped of team captain status after racking up charges on a Des Moines woman's debit card.
Orie Lemon, LB, Oklahoma State
Lemon was what you'd want in a linebacker mentally and physically when he was healthy, but his torn ACL last season hurt his draft stock. He's a big hitter, too, but at 242 pounds, NFL teams didn't love his speed.
Dan Bailey, K, Oklahoma State
Simply put, kickers don't get drafted too often. Bailey, who won the Lou Groza Award last season as the nation's best kicker, should get his shot at some point.
Colby Whitlock, DT, Texas Tech
Whitlock has great size at more than 300 pounds, but his lack of speed concerned NFL teams, who also weren't in love with his pass-rushing ability or overall athletic ability. I've been a fan of Whitlock's technique during his time in Lubbock, but measurables are more apt to get you selected.
Jerrod Johnson, QB, Texas A&M
Not a snub, per se, as it was pretty obvious that Johnson struggled in the events leading up to the draft, especially at the Senior Bowl. But Johnson likely would find a shot somewhere, and it's still shocking to see a player with Johnson's resume go undrafted. Coach Mike Sherman knows the kind of football mind Johnson has, though, and can sell his NFL connections on it. There's no question he'll end up in a camp once the option is available.
