He didn't suit up again after the 49er game when he filled in admirably for Smith at LT. Having the swing OT active on gameday is always a need, you just never know when he actually needs to play.
For the record, I think Chaz is better than Free at this stage and would have taken his job last year. But I'm glad the team signed Bell because there is no reason to believe Chaz will stay healthy. He was injury prone at UF also. But if healthy, I think he will be good and the fact he can slide to LT provides nice position flexibility also if Tyron misses a couple games.
