If you had a time machine, and you could go forward to see what would become of the Cincinnati Bengals this season, it'd be pretty easy to deduce why they might not win the Super Bowl.
Both sides of the line of scrimmage have their problems in Cincinnati. The right guard position is ghastly at the minute, and the general state of the defensive line sans Trey Hendrickson is not-great-Bob levels of concerning.
Without many major players hitting free agency in the next couple years, the Bengals have a chance to really build through the corresponding drafts.
