I think we can all agree that Cal just has not done a good enough job coaching. But I think this roster has severely missed the mark on so many fronts. Oscar is wilting. CJ is injured and scared. Toppin turned out to be overrated. Livingston is a multi-year player. Cason isn't really a PG (not yet at least). Wheeler is big flaws. Reeves is proving that while solid, there's a reason transfers didn't start at Kentucky..
When it comes to roster changes, at some point you just have to stick with what's working "well enough" than try and get someone else going. The mistake was that we should have been playing Ugonna, Collins and Thiero more in the early going. But it might actually be too late now. It very well might be better to stick with Oscar in hopes that a few more 15/15 games get us into the tournament, than roll the dice with trying to get Ugonna up to speed.
It's still Cal's fault, but this team just isn't that good, and I think even Cal was a bit surprised at just how far off they are.
