I think Hagler was the wrong match up for Tommy. Marvin was just too good at everything and had a granite chin. If Leonard could make Tommy wilt, I have no doubt Marvin could as well.

Tommy was an amazing fighter, but just flawed enough to make every fight exciting (these fighters tend to be more exciting than the truly dominant/fearsome fighters often). I would have loved to have seen Tommy in hypothetical match ups vs Toney, McAllum, Norris, Benvenuti, Griffith, Trinidad...etc. He's probably the fighter I most put in hypothetical match ups (I'm a dork and visualize fights while I run) because he was such an exciting fighter with so many tools at his disposal.
