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.
Tyler Eifert. Watch his 2015 film, dude had the potential to be the next great tight end in the league, but was derailed by injury. Damn shame, dude was insane in the red zone
