Far from me to defend BADOL, but his take on Star is spot on so far this year. He gets neutralized far too easy. On one egregious play he got pushed back so badly it looked like he was wearing sneakers on ice. I think that teams are realizing that he doesn't need a double team, which spells bad news for Oliver.
That doesn't mean that the obvious response is that Bills should never have traded Dareus. Looking at Jags game tape reveals the bad-habit Marcel whose performance doesn't look too much different from Star's, and you can't discount Star's positive influence in the locker room culture vs Marcel's.
I also wouldn't discount McD looking at the practice squad to improve the interior line and for Star to develop a season ending injury. Bills can cut ties with him after the season with a post-June designation and walk away from the contract after paying all his guarantees through this year. He can also agree to the paycut similar to the one Dareus took to stay with Jags this year.
