How is he disappointing? He's improved in year 2, and IMO, improved A LOT on the defensive end. That is a huge step for a center to make in his 2nd year, while also dealing with a 25-game suspension. I'm not sure what else you want at this point.
We live in an era that has already seen Shaq and Dwight Howard dominate the position. OF COURSE he's going to talk about wanting to be the next great center. I'd be more concerned if he didn't have at least a little bravado.
I just don't see the problem here. He's improving and that's what matters.
His defense has improved but that doesn't mean there isn't more room for growth. He needs to learn to work in the post and create his own shot so our guards don't need to feed him so low and he's not so dependent on others getting him going. He's talked about how he'll come in and take over yet we haven't seen anything close to that so far. Surely he's capable of envisioning it but actually carrying out that plan is another story. If he can't do that then he needs to quit saying he's going to do it. He also needs to learn to finish through contact as well as initiate contact on his inside shots so he can get to the FT stripe more often and get the opposing team in foul trouble.
Sure he was suspended but that's no excuse. If anything I blame him for the teams record since he couldn't properly manage and control what he put in his body. He let his teammates, the organization, and the fanbase down by doing so. I hope he learned his lesson but I won't allow his 25 missed games to be an excuse as to why he might not be where we'd hope. If he suffered an injury that sidelined him for that long, I'd cut him more slack but his suspension shouldn't be compared to an injury as far as time missed. He was healthy for that time off and should have been working hard on improving while he was away from the team. I think he did work during that time but I'm not sure how hard he hit it. I know he didn't take the league by storm when he returned, like he said he would.
Another issue with his suspension is it started with more empty words from him. Right when it was announced Ayton tried getting in front of it by denying wrong doing and saying he'll appeal it. He even seemed to convince the players union to back him for that with talk of it being fast tracked. As we know now, that didn't happen. He said after he returned that he decided to take his suspension, which is fine, but it says nothing about his comments about appealing it and how he was done wrong.
He was a #1 overall pick like Howard and Shaq and he has all of the physical gifts and IQ to be as good as they were in their primes but he has to learn to channel his aggression on the floor and dominate a game. I want him to live up to being a #1 overall pick in that I want other teams to be jealous the Suns have him and covet him. I want him to look like an All-Star now since there have already been 2 other players from his draft class that have earned those honors.
