You might be right TW, but coaches say a variety of things throughout the season. I don't particularly recall the interview you are talking about but I'm absolutely sure it's true.
Do some players get in coaches doghouses - yes. At the same time, I find that different players need different motivation. Sometimes in a particular interview or article it seems like a player is the punching bag, but I would say that over the course of the season Gard has been pretty fair when talking about Pritzl, and that Pritzl himself knows his own head-space is part of his problem.
This article from December would seem to indicate that both Gard and Pritzl know he has things to work on:
Wisconsin State Journal - UW B-ball
Do I see coaches being somewhat critical - yes. Do I see a player who acknowledges that he has thing to work on, and that he's inconsistent, and needs to get out of his own way in his head - yes.
Similarly with this article:
Wisconsin State Journal article on Pritzl's shooting woes
I agree that Trice has gotten a bit of a pass on his play, but this year he hasn't played much so I don't know what Gard would have said about him over the course of a whole season. It's always been that way with certain players - I don't know why. Maybe it's because coaches know that some players handle things differently so need to be treated somewhat differently.
In the end, for me, it's not about what coaches say, it's about what they do. Players they don't trust don't get minutes, especially important minutes down the stretch in games. For me, Gard clearly has trust issues with guys like Van Vliet, Thomas and maybe a couple of others. They don't get consistent minutes because he knows they can't be trusted over the long haul. I think Gard's actions tell me he trusts Pritzl more than most because he gives him big minutes consistently and has him in the game during important stretches.
Next year could be a whole different animal. Trice and King come back and Trevor Anderson, the talented transfer from UWGB, becomes eligible. With 3 more guards among which to distribute minutes, it'll be interesting to see how things play out for Pritzl and everyone else. I suspect Davison starts at the "2" spot next year with Trice getting the start at the "1". Ford is likely purely a "3", getting minutes when Iverson comes out of the game and at the "4" when they go small. King might get some minutes at the 3 as well as the 2. Pritzl probably gets most of his minutes backing up the "2" spot when Davison is out, or when Davison slides over to the "1" to spell Trice. Too hard to predict what minutes Anderson will get, if any. Lots of guard options next year. We'll see where Pritzl lands.
