He didn't run at the Combine. lol, those horrible numbers are from his pro day on the March 8th. It's why he's fell back down to a borderline first rounder instead of a middle first round guy.
I was referring to the combine, not his Pro Day.
A 4.6 however is not horrible speed for a SS. Its not elite speed but it's far from a deal-breaker. Kenny Vaccaro ran a 4.6 too.
