1. Aaron Hernandez
Hernandez and Rob Gronkowski struck fear into the hearts of opposition teams. The Patriots duo were two of the best tight ends in the sport. However, Hernandez never achieved his full potential because he was a murderer.
On paper, Hernandez was a phenomenal athlete, who combined wideout speed with tight end strength. However, his struggles evolved into something much more toxic. He should have been one of the Pats’ biggest heroes (via Fansided).
