​There might be no one on this planet who knows quarterback knee injuries as intimately as Robert Griffin III does.

The Heisman Winner turned rookie star turned medical case is no stranger to the type of knee injuries that derailed his career--so when he says something about the subject, you better listen.

This is what RGIII had to say right before Vikings QB and fellow ACL injury support group co-chair Sam Bradford left a game he was clearly never meant to play in:

​​Bradford, who had missed the last two weeks with a knee injury, was inserted into the lineup by coach Mike Zimmer today, and wasn't pulled until late in the second quarter, despite it being obvious from the get go that he wasn't in game shape.

​​That Bradford was taken out was a matter of when, not if--and it looks like RGIII knew exactly when.
