I think you guys are missing the point. Clearly Kanter was Gobert's mentor and the sole reason why Gobert is so great on defense.
If that article allows you to post comments someone should go bring that up.
As for the OP, I don't feel like addressing all of the fallacies in what you assume to be facts but I will state one thing that has been mentioned in the countless threads and by media. He had more assists in his first week or two in OKC then the last couple months on the Jazz and this showed he has the ability but he had a poor attitude while on the Jazz, for whatever reason you want to blame it on.
Other Jazz players like Favors, Hayward, Gobert, Burks all lived through those same times, coaches, experiences etc... but they moved past it. Kanter did not, again for whatever reason. I do think a large part of it was his agent, if his agent had been a better mentor to him IMO things would have worked out much better for Kanter, even if still on another team.
