I know some will argue we cycle through coaches too much so keep him for stability.
This season however is too important to run out an up and down, spread offense system which doesn't fit our best players while our defense looks as unorganized as ever(product of poor game planning from the coaches).
Fire him? Too early for that but priorities need to be changed. Need to focus on the halfcourt offense and our defense. Stop immediately turning to small ball like an addict. We're dropping games we should be winning and this season is a bottom line business, wins are the only thing which matters. That's it. There is no more patience, time to build, grow the youth, get a good pick, etc, it's playoffs or bust.
As I said, too early, I'll wait a few more weeks but I also said this past summer not firing Karl would be a mistake. So far I'm not seeing anything suggesting that was wrong.
