It's why I love the NFL. Plenty of uncertainty and this division is no different:
-Ravens: Will Lamar keep up his fantastic play or will he regress? IF he regresses (in terms of production), to what extent?
-Steelers: How effective will a healthy but older Big Ben be? I don't think he'll be trash or anything like that, but will his age show?
-Browns: Will Baker and the rest of them mature from their foolish ways of last season? How will a slimmer Baker fare?
-Bengals: Pretty self-explanatory as to the question marks surrounding them.
