Fullmer used a fair bit of movement in their second fight after Webb had him down (not ruled) a few rounds in (2nd fight this, which I must upload because this keeps coming up!)
Anyway, if Tommy boxes I think he might well be able to evade Webb. By the same measure, if he lands a beauty on Webb as he did Schuler there's no guarantee Webb can get himself back together as he did against Boyd.
But I'd favour Webb to close the distance after being stung and force Tommy to punch it out with him; then it's Webb's game. I say he lands some damaging shots to force a stoppage as he did with Giardello (was it cuts? In the footage I just remember Joey getting battered)
Webb KO 7/8
Hearns winning is so very possible I'm not really ****d either way. Great matchup
