NFL

Shaq(Darius) Leonard had an all-time start to his career and then had 2 back surgeries and is pretty much our LB3 now. It sucks, he was fun to watch before the injuries

Ki-Jana Carter would have been one of the greatest RBs ever

Pennington. Both in New York and in his second act in Miami. I remember how good he was in 08, and I though we would be good for a while. But only a few weeks into 09, he suffered a career ending injury, and the walk in QB purgatory resumed

Todd Gurley was well on his way to being one of the great RBs. injuries are a binch

Ryan Shazier was a future HoF line backer. He was fucking nasty. Before he got hurt only Luke was at his level at MLB. Steelers defense immediately went to top 3 in the league with his breakout. They tried replacing him like every draft he was so impactful.

Bo Jackson would have been really cool to watch have a full career.

Jason Verrett - dude was playing all-pro level his rookie year and whenever he was on the field he was shutdown... but unfortunately he could never stay on the field.

Jahvid best man what could’ve been

Obviously someone like RG3 could’ve lit up the league if he didn’t destroy his knee.

If Bo Jackson didn’t get injured he could’ve held every RB record ever.

If Johnny Manziel didn’t go to a poverty franchise like the Browns it could’ve been possible with proper coaching he could’ve been a great scramble QB.

See the 30-for-30 on Marcus Dupree called "The Best That Never Was."

Dude had SO much potential in an era where running backs like him became legends... Emmett Smith, Barry Sanders, Eric Dickerson, Hershell Walker... he could have been at that level.

Feel like nkeal harry got a bad beat super early in his career even rookie year with brady left alot to be desired. But brady never had a great connection with rookie recievers. Then was move from bad situation to worse hoping he gets onto a practice squad somewhere and starts balling

Sean Taylor, Bob Sanders, and Chris Henry

Jason Verrett :(

As a Browns fan, the first one that comes to mind is Tim Couch. He was picked out of Kentucky to be our first QB of the re-born Browns in 1999. He had all the tools, and seemed like a really decent guy as well. But the owners failed to put protection in front of him and a solid team around him, despite a really favorable expansion draft deal. He got pounded into oblivion behind that O-line and was never the same again. They destroyed that man's career, and set the franchise on a downward spiral that they're just STARTING to climb out of.

I have often wondered how good David Carr could have been had he not been drafted first, overall by the Houston Texans. They had no offensive line, and he was eaten alive.

It would have been better for him to have been drafted by another team, to get some seasoning behind an established quarterback.

I would have liked to see Charlie Ward in the NFL. He chose basketball instead but would have been a top pick in the NFL.

Clarett

Sam Bradford

Surprised nobody said David Johnson. Dude was a freak for a few years, injured his wrist week 1 and was never the same. Lost the burst and power he had.

sterling sharp.

Rg3 injuries killed his career but damn he was special

Bo Jackson.

Sam Bradford, David Wilson, Victor Cruz, Saquon Barkley

Here's a curveball idea: Jay Cutler. If the Broncos don't fire Mike Shanahan, McDaniels doesn't ship Cutler off to Chicago (where QBs go to die). Chicago still has never had a 4k yard passer, Cutler did in his last year in Denver.

Reggie Bush

I feel like dk metcalf hasn't hit his peak
