If this Combine had a theme, it's the big players stepping up and cementing their status in the top 15 of the draft. The defensive backs look no different.

LaRon Landry, who earns the nickname "Popeye", seems like a lock for the top 10-12 picks after running a 4.35. Combo safeties like him gain in value every year.

There were some speed questions about Michigan's Leon Hall, considered by many the best corner in the draft. He put those questions to bed with a 4.39. That should help him get taken in the top 15.
