Yes last season was wasted. Wasted by signing a QB who was suspended for 11 games. But don't let that fact get in your way.
The offense was good enough to win the entire year last year. I did not see that team wasted on a suspended QB at all. Brissett was more than good enough and should have won 3 more games and been 7-4 instead of 4-7. It was Woods's defense that wasted the year. Thus, the FO went and got Jim Schwartz.
