The NFL season is now at the halfway point, but almost every team still has a few question marks that leave me unsure about their capabilities.
For some, this uncertainty revolves around a key player who is falling short. Mario Williams is one of the first to come to mind.
Others teams have less individual problems, and as a result, these may be more difficult to resolve. Can New England’s secondary be average? Are Indianapolis’ troubles stopping the run going to ultimately eliminate it from playoff contention?
These are just a few of the biggest question marks midway through the 2012 NFL season.
