14. Aaron Hernandez
Hernandez was a tragic and twisted human being but a phenomenal football player. Make no mistake, the dual threat that Hernandez and Rob Gronkowski offered the Patriots was unbelievable. The tight end was had incredible physical gifts that separated him from many of his compatriots. He had 18 touchdowns and 175 receptions in 38 games, with just under 2,000 yards.

Nobody should make light of his horrible crimes because his actions were pure evil. But from a sporting perspective, it’s fascinating to consider how good he could have been. Hernandez had so much potential but his wickedness prevented him from showing it. In 2021, Gronkowski told the Kyle Brandt Podcast (via Yahoo) that “Hernandez was a great player, but that means nothing.”
