Exactly. If the best that fans can come up with is "he looked hurt against Seldon," that hardly changes the fact that McCall has arguably the best chin ever at HW. The only argument, imo, for putting Chuvalo ahead of him is he fought in a better era.
Mccall has never been down in 22 years of boxing, with a decent resume as well. Mccall's chin is a legend in itself.
It's only a shame he can be beaten by someone who boxes and moves and outworks him. He would've rocked in those medieval contests where they used to take turn to hit each other!
Lewis would have knocked him TFO in their second fight if it hadn´t been stopped though. McCall really wasn´t defending himself and nobody can just keep taking flush punches from someone like Lewis.
