I've always thought that Toney had the style to beat Hagler, the way he counters off the ropes, the toughness, the infighting skills. But the thing is this those skills that he had, the shoulder roll, pull counter right hand, were not fully developed when he was at 160. He was still young, didn't have a whole lot of amateur experience, and he was still perfecting all that while he was there. Look at the fight with Merqui Sosa, you almost don't recognize him. In the Nunn fight he started to come along, he had a rough time early, but he was starting to land those pull counter rights. But its still not a fully developed Toney. You can see it again against Reggie Johnson, getting there but not the fully skilled Toney, he was legitimately stunned by the light hand KD in the second round and although he's a good defensive fighter by that point he's still getting hit cleanly more than he did later on as he fully developed his style. Not saying he was not a very good middle, to beat Mike McCallum, Nunn, and Reggie Johnson you have to be a good fighter, but he's not the incredibly skilled, crafty defensive fighter that he became. A very good defensive fighter with more craftiness than you expect from a fighter that age, along with good handspeed, power and toughness but its not a fully developed Toney.

Plus he had trouble making 160.

So I don't know, point is the Toney at 160 was not quite the same fighter that he became, a very good one definitely but not quite as crafty. I'd probably favor Hagler by decision over the young Toney that fought at 160.

Written enough for now, I'll post on the other two some other time.
