Marcell Dareus was a 3* (.90 by 247) and was drafted #3 overall after an incredible college career.
Chance Warmack was a 3* (.86 by 247) and became one of the best guards I've ever seen. He was eventually drafted #10 overall.
Vinnie Sunseri was a 3* (.86 247) and was drafted in the 5th round - was recruited as a linebacker but was an all-SEC/American level safety before he was lost his final year to injury.
Terrence Cody was a 3* (.88 247) and was drafted in the 2nd round.
I could give more if you want.
