I haven’t watched this in a while but had Ali winning. I think he looks much quicker & stronger in the second Frazier fight though. He looks like he fatigued more in the 2nd Norton fight. Maybe Norton just put more pressure on him & pushed him more. I just think the Frazier rematch is the fastest he looked & best he moved in the 70’s. He did look great in the first Frazier fight but didn’t move as well.
Norton didn't put more pressure on him imo. He tired due to his own fatigue unlike the first fight with Frazier, when Frazier's body shots slowed him down.
Here's how I scored it not sure how you can give Ali 7 rounds tbh I can maybe see a draw. Muhammad Ali vs Ken Norton II Round 1 10-9 Ali Round 2 10-9 Ali Round 3 10-9 Ali Round 4 10-9 Norton Round 5 10-9 Norton Round 6 10-9 Norton Round 7 10-9 Norton Round 8 10-9 Ali Round 9 10-9 Norton Round 10 10-9 Norton Round 11 10-9 Norton Round 12 10-9 Ali 113-115 Norton
