Knox has been rehabilitating for an entire year and expects to play in 2013. The Bears have spent big at WR on others so he likely won't return.
If he can pass a physical he will be the very definition of a mid-level FA signing.
He is a Texas kid and pure speedster who replaces Austin's game breaking ability. And we have a starting spot open.
I definitely agree though he'd have to pass a physical and that isn't guaranteed.
There are other WRs I'd rather have and I think that position has to be addressed if we release Austin but I tried to be very realistic about the state of our cap space and look for complete bargains. Others here have used 5+m per year guys as mid-level.
I look at him same as Columbo whom we also salvaged off the Bears scrap heap after time to fully heal.
