What fighters do you think quit a little too early?

Junlong Zhang. He hasn't officially retired but it's been years since he had a fight. He says he'll be back against a WBA rated opponent, though.

 

Carl Froch had plenty in the tank still was hitting all his training record times etc... should have fought GGG...I would favour him at SMW

 

Then moved to light heavy weight ...no doubt in my mind he would have beat kovalev then retired 2 weight champ

 

Hagler after the Leonard fight.

 

Michael Spinks

 

Not falling in love with his power after he beat Steve Robinson, not letting his brothers meddle, and not leaving Brendan Ingle certainly would've helped his cause too. But in Hamed's defence, I think he did say that by the time he fought Manuel Calvo he simply had no more hunger left for boxing anymore.

 

I was gutted that Pirog had to retire due to the persistent back injury: Pirog vs GGG would've been a great fight.

 

Going way back, Jimmy McLarnin. Retired just shy of his 29th birthday with his health and wealth intact -- an extreme rarity in the fight game. It's hard not to respect that.

 

PED's? What proof is there Ward was a PED cheat?

 

It was WBA sanctions, according to him, they removed him from their rankings. The reason he stopped boxing entirely is that his team wanted him to not take damage before they found a contender who would fight him. Per Asian boxing.

Seemingly, no contender was up to the task, either for financial reasons or otherwise.

 

I always thought Pavlik had a couple great wins or at least damn good fights left in the tank

 

Groves. If he hadn't made that guy a vegetable maybe he would have pushed on a bit. He retired very young by today's standards.
He left some big/interesting fights out there.
Groves - Saunders
Groves - Canelo
Groves - Ward
Groves - Bivol
