What player in the NFL, past or present, would you have wanted to see succeed so badly but due to injuries, off the field issues, or whatever happened just derailed their career? For me it was unfortunate to see players like Josh Gordon or Justin Blackmon have their careers end or never getting back on track because of off-field issues.
Aaron Hernandez. Could have been an all-time unstoppable TE duo with Gronk. Showed flashes of greatness together.
Sadly, gangs and murder and CTE combined to erase that brief brilliance on the field.
