In my opinion Toney was not the fighter at 160 that he became at 168, 175. But he was still really good. He beat McCallum, and I think Mike would've beaten Hearns.
Tommy's big weapon was always the right hand, and that plays right into Toney's (right) hands. About that time, Hearns was working a pretty good left hook to the body into his game plan but I don't think he would throw that much against Toney. Hearns couldn't fight a lick inside and hooking the body would bring him and Toney real close real fast.
Hearns wasn't too durable. Toney would stop him in 8-9 (remember, DeWitt hurt Hearns to the body, and Olijiade-spelling?- was on his last legs and seriously hurt Tommy with a hook).
