He can’t stay healthy long enough.
Saying he’s not injury prone is one of the most demonstrably absurd things I’ve heard suggested on this board.
The two injuries that cost him the most time where fluke occurrences (especially the Warren injury). If he doesn't have those he's just a regular player who had a hamstring strain and ankle sprain and we wouldn't think anything of it.
The only injury he's had that is worrisome for future injuries is the ACL injury and he hasn't had any knee issues since.
