When will Zac be fired?

[Bengal Dude]

I know earlier in the offseason Jay Morrison mentioned that if the Bengals start the first quarter of the season slow that he could see the Bengals pulling the plug on Zac. I was thinking it'd be more of a bye week thing to give Simmons a little more time to implement himself, but I could easily see the team giving Zac the whole season barring a catastrophic meltdown in the locker room.
