You're seeing pro days start to come and go across the Big 12, and the NFL combine wrapped up late last month. With all of that, there's plenty of shake-up in the position rankings from NFL draft guru Mel Kiper. Here are the Big 12 guys who cracked his top five at each position.
Geno Smith moved into the No. 1 spot for quarterbacks, ahead of USC's Matt Barkley. We'll see if that changes with a good pro day from Barkley, but Smith definitely has a shot to crack the top 10, especially after Buffalo cut Ryan Fitzpatrick loose on Tuesday and looks as if it's in the market for a quarterback with the No. 8 pick.
Tavon Austin secured the No. 1 spot with his huge day at the combine, sliding ahead of Cordarrelle Patterson. It's not quite a consensus if you look at other mock drafts, but Kiper's buying what Austin is selling.
Oklahoma's Lane Johnson is rocketing up draft boards now that scouts have had a chance to see what he can do athletically. He's No. 3 on Kiper's list of tackles, despite not being an All-Big 12 first-teamer a year ago.
Texas' Kenny Vaccaro is widely considered the most complete safety in this draft, and he held strong with a good combine performance. He's still at Kiper's No. 1 spot.
Oklahoma State's Quinn Sharp's recent rough pro day wasn't factored in, but he's still No. 4 on Kiper's list.
