Here is my worry with THT. I think he is improving. I think he's fun to watch. I think my issue with him long term on a team that wins at a high level is that he will likely have flashes of amazingness and flashes of cringiness. When he is in a smaller minute role I am not sure he will get the chance to work through the valleys. I am glad he is getting a lot of time to hopefully get the decision-making stuff figured out and work on consistency. Improved decision making and better shooting will really help those thing smooth out.
While I understand this line of thinking....the other side of this coin is often used in favor of players. He might get in a game for 3 minutes, completely stink it up, and never get a chance to make up for it. But he may also get in the game for 3 minutes, play well, and he won't have the cringeworthy moment because he's already subbed out. When we talked about Dunn/Shaw Harrison, it was a common talking point that we liked those guys because they add a change of pace and their flaws were not that big of a deal.
I think it's good to have some guys who provide consistent value that you can rely on. But when it comes to guys who are highly variable, I'm not sure it helps or hurts the player in question. I know coaches strongly prefer the more consistent option but having a guy who is a little bit of an X factor isn't the worst thing ever. A good balance is nice,
