The altitude will unquestionably give him the conditioning advantage at 175 that he needs, his style requires it and benefits from good camps. When I was younger I used to train a lot at 1500-2000 km, albeit as an amatuer, but the advantage is no joke, you come back to sea level and feel like you can walk on water (even if half of it is placebo). This principle multiplies the heavier you go up in boxing imo, so at 175 it's the perfect storm.
I'm not as harsh on Morrell as you, he fought exceptionally against Benavidez, just didn't quite get it, but on another day he might have.
The Khaetev fight was a tough slog, but Morrell still had great periods throughout, Khaetev is no joke, bronze medal Olympian and Chechen PEDS maniac, thats a frightening proposition for any opponent.
I'm expecting a knockout against Callum Smith, who is an underrated boxer mind you, this is a good fight, 175 is definitely one of the best weight classes these days.
I'm not harsh on him about Benavidez as I expected him to lose. He showed a lot of grit in that fight. I know Kaladjzic is a good fighter but Morrell's offense was really poor in that fight and the scorecards were absurd. Khataev, he had good moments but he didn't use enough of his smarts in there. I thought that fight was close on the cards anyways. I think someone on here said he'd had a bad camp and it reflected in the ring. I'm still rooting for him. He has a lot more ability that he used to show at 168. I think when he started getting more early knockouts he abandoned the boxing that he displayed against guys like Lenox Allen. I think if he finds that balance he can become a champion. That Callum fight should be a great one.
