Good news is that he is injury prone (missed 25 of 64 games) , was ranked horribly as an OL for all 4 years he has played, and is overpaid in total, with 7mil guaranteed.
Sounds like he is a perfect choice to join the cable OL circus.
He should be in just enough games for us to see how truly bad he is before he has a season ending injury. Then he just becomes dead weight against the cap.
Hopefully the FO keeps enough in reserve for a couple leg braces and a wheelchair for Russ.
