I still firmly believe that Aldon Smith would’ve been one of the best defensive players of all time if he just stayed out of trouble

Tommie Harris was a beast before his hamstring was torn in 2006.

Sean Taylor could’ve easily been the best of all time at his position

Percy Harvin

Justin Blackmon would have been a top end receiver if he could've given up weed and booze.

If Jags had given Blackmon the support he needed, he would have been a generational talent. Knucklehead organization in a knucklehead NFL era though.

Frank Gore entering the league without 2 shredded knees.

RG3. Guy could’ve had a HOF career

Dan Morgan would have been an all-timer if not for the injuries. He broke his leg after 11 games his rookie year, had 5 or 6 concussions, partially tore his achilles, and had several other injury issues after having no real injuries in college. He still holds the Miami career tackle record.

Johnny Manziel.

Janzen Jackson https://en.m.wikipedia.org/wiki/Janzen_Jackson

Terrell Davis was an absolute machine but ended up gimped by injuries.

Shazier easy

Ryan Shazier

Joe delaney died at 24 trying to save drowning kids. He had Chiefs records that stood for over 20 years. Id loved to have known how good he could have been.

Johnny Knox

My good friend swears up and down that Denario Alexander could have been a star in this league of it wasn’t for injuries. Dude was 6’5 with Great hands and a decent 40. Sadly he just couldn’t stay on the field.

I really feel like Brady Quinn would have been more successful if he didn’t land with the Browns.

Justin Blackmon.

I think AJ Macarron seriously could win the Jets a Superbowl right now. A dink and dunker can work in this league. I was sad my Bengals did him dirty. But how could you bench the red rifle after 2013?

Ricky Williams could have gone down as an all time great if not for his off the field stuff.

Josh Freeman.

Oh, Josh. I just hope you're happy and healthy, man.

Odell Beckham Jr

Patrick Willis

As crazy as that sounds. His injuries cut an already HoF career short.

The world was robbed of Sean Taylors greatness. The fuckers who killed him breaking into his home got off easy. RIP to the most fun defensive player I can remember watching

Victor Cruz deserved more time at his peak. If he stayed as good as he was he could have been a HoF contender

Lev Bell,

I want to know what kind of player Travis Fulgham could have been if he had better work ethic. Those three weeks he had on the Eagles were awesome and then he just stopped trying

Ok, I'll say it.. Aaron Hernandez. Horrendous person off the field, but he had the on field talent

I was always a huge Bob Sanders fan. He did succeed with a SB, two first team all-pros, and a DPOY award, but his prime/career was cut horribly short from injuries. He only played above 6 games twice in his career, and racked up all those accolades listed above in those two seasons alone.
