Saying it's hard to follow up a Heisman season would be is a massive understatement. If you're fortunate enough to receive the prestigious award, there's a good chance you had a unbelievable season. That means when you return the following year, you're not only expected to as good, you're expected to be even better.
Louisville's Lamar Jackson became the first player in FBS history to pass for over 3,300 yards and rush for over 1,500 yards. As asinine as it sounds, if he's not able to surpass those numbers from a year ago, some national pundits will claim it's not good enough to be awarded the Heisman trophy for the second time.
Don't expect Jackson to have a Heisman hangover in 2017, but it's important to remember that expectations may be unrealistic.
