Did he?
I'd say he helped himself a little. He didn't go crazy or anything but of those classed as a safety he had the second fastest 40, highest vertical, and was up there in bench. Pretty balanced performance. I always thought he would be drafted, but late. Now he may go in 4th or 5th round instead of 6th or 7th. His hitch is going to be in coverage. If you're looking for a box safety, then he could be pretty good.
