i never give up on Rodney, he can play until he is 40 it dont matter to me, he was/is the heart and sole of this D since he got here. He can do whatever he wants if he wants to retire thats ok too hes given us more than expected especially after his 1st knee injury.
Just a thought though...
looks like he hurt the outside of his left knee, i think that is an acl? Was the same knee he blew out before, so maybe he cant come back from it. But its early in the season, if he has surgery quickly he could rehab with Brady and come back one more year for one more run at it. Start on the pup would be ideal.
