I agree that OBJ is in a bit of a tight spot here.
On the one hand, teams will be worried about the knee and hesitant to sign him for big $$ this offseason if they don't see first that he can still be a force.
On the other hand, if the knee pops again he's done.
It sucks for the player, because he was on his way to a possible Super Bowl MVP type performance when the knee went out and let the Bengals back into the game. But with the ACL tearing 2 years in a row and him getting up there a little in years teams are going to be cautious.
