It's Riyadh Season, Netflix, everyone around this fight... You can see how big it is. You have two of the best pound-for-pound fighters fighting each other, so Saturday, Sept. 13, we see who's the best."Terence Crawford's training partner previews Canelo Alvarez fightTerence Crawford's training partner and friend, Steven Nelson, recently shared his thoughts on the upcoming Canelo Alvarez fight. He claimed that he's seen Crawford sparring with super middleweights and bigger boxers for years.In an interview with The Ring magazine, Nelson opined that Crawford's power would be a problem for Alvarez and said:"Every time 'Bud' steps up and fights new guys, since he was at, shoot, 135 [pounds], 140 [pounds], it’s always, ‘Oh, I don’t know how he’s gonna be able to take this pressure. This guy’s bigger.’ It’s always that. But since I’ve known Bud, he’s always gotten in there with bigger guys and made statements and ended up being the bigger man. I’ve seen it, I’ve felt it."He continued:"I’m a bigger guy, and we’ve sparred countless rounds, and I’ve seen him in there with so many people, including Lester [Martinez] and everybody, and that’s never gonna be a factor. It’s not gonna be a problem. Bud has always been a heavier guy, but he’s always had to go down, hold his weight. He’s never had a chance to grow.” [H/t: The Ring]
