Could this be the most pivotal bye week of DAs tenure here?

I think it is. This is the time to make real changes. He looks very reluctant to make any real changes QB, OC, OL etc.

The O line is only facing one good defensive team left on the schedule........TB 7th best D. We have to make the O line work. That is what byes are for!!!

Could Carrs concussion, and Injury on his throwing shoulder force DA's hand?

IMHO: We are not going anywhere with Carr if he isn't 100%

I am not a big fan of the 2 QB system, But Jamies and Taysom are a great tandem, especially in the red zone. I think both QBs are useful and can score in the red zone. Jamies has a better TD to interception ratio in the red zone then he has anywhere else on the field. Split the snaps anyway you like between Jamies and Taysom. Carr just isn't scoring enough points.
