I think there is a case to be made that Ty is getting better, at least in some areas like pnr defense. But I'm not one to make it because I think his rotations this year have been as bad, or worse than they were his first full season as head coach. But this is about looking towards the future.
At some point I heard that Ty said Kanter on the bench wasn't a permanent move and he could start based on match ups. That hasn't happened yet. Kanter is playing much better in his last few games, while Marvin's hot start has significantly cooled off. Clearly Kanter has played better recently than Marvin has, so it would make sense that if the match up was right, now would be a good time to start Kanter. You are never going to be able to guess what happens next.
Tomorrow night the Jazz play the Detroit Pistons. One of the biggest teams in the league. Does anyone in their right mind think that Marvin Williams will be able to guard or box out Greg Monroe? Seriously if you can think of why this isn't the perfect time to put Kanter back into the starting lineup, speak now. And to be honest the next night it makes sense to start Kanter again, because Kevin Love will destroy Marvin in the post if given the opportunity.
So if Ty were to somehow magically decide that Kanter makes more sense tomorrow night than Marvin, without sickness or injury being a factor, I will happily and freely admit that I have been wrong and Ty is improving as a coach. And if not? I know I gave Ty every opportunity to prove me wrong and can continue to bash him with my hands clean.
