What they really need is a true center while Hayes is trying his best to be their center, its not enough the guys is young and needs to develop, in the crucial moment he is learning, someone who can defend at the moment, Ayton I'm not sure, if he can play again like before, some news he got issues, if he will be an issue with the team then they will go down, no disrespect but if he can focus and make blocks rebound, then they are good, but if he will go whining that's a different story.
Hayes is actually good one but they're not giving him the longer playing time that they need. But if it's given to him, sometimes he's inconsistent and that's why the time that should be for him was changed and didn't went for him. Ayton has got some numbers and he also scores, so having big man like that is what they really need. IMO, they can get all the big men that they need and still underperform if there's no chemistry to the players that are playing altogether inside the court. That's what they are probably practicing right now, to have the right chemistry.
