Here's what McShay had to say about the Big 12 prospects who were in his top 32.
No. 3: Landry Jones, QB, Oklahoma: Jones continues to put up huge numbers in Oklahoma's spread offense, and while he trusts his arm too much at times, Jones shows excellent touch, the ability to change speeds and accuracy on the run.
No. 10: Justin Blackmon, WR, Oklahoma State: A strong route-runner with elite ball skills, Blackmon has excellent body control and good awareness and strength as a runner after the catch.
No. 25: Ronnell Lewis, DE/OLB, Oklahoma: Lewis is in the middle of a breakout season. He has an impressive combination of burst, lateral agility and body control when bending the edge.
