Some logic fails in this thread, in my respectful opinion.
First of all, it hasn't gone well in general, obviously. And Nixon has gotten a lot of minutes, has done a few things well at times, but can't arguably be said to have played great this year. And it's the coach's job to make changes to address the fact it's not going well.
Also, some rumors I've read on other sites are that Bergersen and Baxter have been progressing this year in practice and deserve to play more based just on that. And you would have to think they were the primary beneficiaries in playing time in the last game from Nixon not playing. Nixon does some things well at times, but I don't think many would argue that those other two guys don't have a lot more upside. Consider the numbers from Saturday:
Bergersen and Baxter in 16 minutes combined for 8 points from shooting 50% from the field, had 6 rebounds, 2 assists, a block and no turnovers. Nixon giving us those numbers would mean he'd still be playing.
When it comes to how the team is doing, of course it's on the coaches. But the fans in the stands can't logically have it both ways. You can justifiably criticize for the team not performing at the level they should be, but when the coach makes a change in playing time to address that fact that actually ended up working out, then also give some credit where it's due.
