It isn't that simple but yeah, that's part of it. His shots are assisted because he doesn't force anything, he takes "his" shot and nothing more. He rarely puts it on the floor and drives so he's not picking up the occasional charge and he isn't using up the shot clock to no advantage as so many bigs do.
I really hate to defend his offense because there are real problems there, I just don't see being assisted at a high rate as one of them.
Earlier in his career we tried to run the offense through him more often and his propensity to fumble the pass leading to an occasional turnover or more often, forcing a reset of the offense after wasting precious seconds was a real problem.
Plus, one of the advantages of running your offense through a talented big man down low (at the expense of the highly favored 3 point shot) is the expectation that the defense will suffer from extra fouls and forced double teams. We get very little of that from DA. But I don't believe we've ever really worked on this.
We accept we're a guard based offense and after giving him a few passes at the start of the game, we forget all about him. It's not because all of a sudden every single team figured out 4 minutes into the game how to guard him either, it's a decision on Monty or CP's part.
And maybe this is the best way to play given the strength of our guards but it's contributing to the likelihood that we will part ways with one of the most gifted players we've ever had. I expect that if we lose him, his next team will force him to become the power inside that he is capable of becoming and we'll go back to complaining about our inability to get a quality big man.
CP won't be here forever, if his presence is contributing to our DA issues that's just one more reason to be patient with Ayton and give him his money. CP won't be here much longer, DA has a chance to be a fixture for us.
