Here's how the Big 12’s best draft prospects fared at their pro days, as well as some sleepers who might’ve helped their chances.
Top prospect: WR Corey Coleman. The speedster feels he proved he’s the No. 1 receiver in the draft after running 40 times of 4.40 and 4.37. Considering he’s coming off a sports hernia, that’s impressive. The Steelers sent Mike Tomlin and all of their top guys to Waco to check out Coleman and DT Andrew Billings.
