Lyle like I've said multiple times. Good boxing does not equate to good striking. Similar but technique wise still very different. I get you don't like it and no issue there, entertainment value is subjective but Mercer who even at 50 was much more talented at "boxing" got his ass whipped by Kimbo, who was a joke of MMA fighter and prior to that was famous for bare fisted backyard fights. Not really sure if Klitschko would beat Brock or not. Brock was really only a factor b/c of his shear athleticism and when tested against top MMA HWs was largely found lacking. Regardless the fact that you use Klitch as your example due to his background in kickboxing shows how difficult it would be for a pure boxer to rely on their superior punching ro beat a quality MMA fighter in the octagon.
