The NFL has built itself into a year-round eyeball magnet. The NFL offseason supposedly begins after the Super Bowl, but in reality, the pro football machine keeps right on turning. The pre-draft showcase and workout season get underway even before the Super Bowl is over, free agency begins in mid-March, the draft happens in mid-April, and then there’s only a few months of (relative) quiet before training camps open at the end of July. Even with no games on the calendar, the league has a way of generating enough drama to stay top of mind.
