I wouldn't be suprised if the team was actively pursuing a trade. Could be why he's not even active. (not risking injury)
Now I don't think we'll net anything higher than a 4th/5th should we trade him, but it's clear the team doesn't see him in their future.
I never had anything against Knowshon. I actually was happy to get him after seeing him at Ga. (still wanted Orakpo there, but w/e). But, as was stated before, in all my years watching the Broncos, never had I watched a player that made me cringe everytime he had the rock in his hands (fumble prone).
