WHAT IF...?

[*ochocincos*]

This OL doesn't have the talent to help get this team to the playoffs this year.
They aren't going to magically improve by leaps and bounds in that short amount of time with a new HC, especially one that's internal.
This season is and always was going to be a grooming season.

But to answer your WHAT IF - I'd still want coaching changes. The current staff has been around too long with unsatisfactory results, so there's no faith that they could get the Bengals to even a conference championship game.
