If the defense improves, I expect it will, and IF the offense can stay as productive there is no reason they couldn't win 10 games. A couple timely plays or defensive stops and this is a completely different conversation. TT is good enough until someone emerges, either Cardale or through the draft/free agency.
The results hinge on so many things that still haven't happened yet so before I see what moves are made this offseason I can't committ to anything and neither should you.
Without looking it up i'd be willing to bet the qb pay is commensurate with the amount of wins the team has, in most cases.
