You can't have it both ways. You can't pretend dismiss criticism of the offense the last two weeks because "Zappe hasn't had many starts" and then try to frame it like Bill is absolved because he finally fixed everything by moving on from Mac when literally all the evidence isn't suggesting that.
1. Bill went into the season with Mac as his starter
2. Bill went into the season with Zappe/Grier/Cunningham behind Mac and didn't believe in them enough to start them until the season was lost.
3. Bill hired BOB and could have had an open coaching search. Instead he did what everyone predicted and got a retread he was comfortable with.
4. Mac wasn't throwing off his back foot neatly as much year one. When the QB regresses, that's coaching.
5. Special teams is his baby, it sucks this year.
6. The defense has been the same story the last few years. Beat up on some crappy offenses and the implode against the skilled ones. That didn't change. They were healthy to start the year. Couldn't stop the Eagles and Cowboys and Saints from piling on.
Yeah Bill wants to be the guy who builds the team, brings his guys in to coach, and oversee every aspect of the team, he gets 100% of the credit and blame. If things were going good, people would be jerking it to how much of a genius he was.
