What got the safety beat was his half ass drop. He was late because he half assed his drop. Watch the clip Tusk linked. He was beat from the get go. I do wonder though if he thought it was a cover 4 because normally in that cover 2 the cb gets a bump on the wr, and it looked as if the safety was playing it as a cover 4. That's the way it appeared to me looking at it again. As Bulldawg28 said earlier it should've been picked off or broken up.
