Sure for the most part Hearns was out muscled by Hagler in their epic 3 round bout.If Heanrs did'nt break his hand,Haglers strength and pressure may or may not have prevailed,if it did it would have been later on I suppose.. But, with Hearns moving up in weight carrying more size and strength,if Marvelous decided to move up to challenge him,(which he never would because He was always at middle) what would have been the outcome?
