When I check off the things that have gone wrong this season, at least relative to expectations, it's a pretty long list. And I think a number of these, the optimism was warranted. Off the top of my head (I'm sure there's more):
On the down side
Skyy Clark as a borderline 5 star PG. A potential one and done or two and done type of player is not replaceable, and leaving the team is about as a bad an outcome as could happen.
RJ combination of injury and/or soph slump. He was so incredibly efficient last year and has cratered more than any player I can recall. That's a tribute to how good he was last year in limited minutes. I think everyone was looking at a break-out player in the making. Hopefully he's 100% down the road.
Goode with a major injury, in an area where the team has the greatest need. Lost some length and desperately needed 3 point shooting.
Defense, specifically 3 point defense. Not sure why this has been a persistent problem, but I assume the switching strategy leads to breakdowns. Overall defensive metrics are solid, but defending the 3 point line has been bad, and teams have made them pay. It's understandable when TJD or some other future NBA guy gets his 20+ points, but the close-outs for open 3s has been hard to watch...
On the plus side
Coleman exceeded my expectations, but I was not expecting a huge leap. The 3 pt shooting is underwhelming, obviously. I think some are disappointed, but he's a definite plus to expectations IMHO. Love his passing, defensive length, and overall game. Has had some great cuts to the basket for easy points and potential fouling opportunities.
Dain has blown away my expectations. Stays out of foul trouble while contributing a ton in every aspect. Hard to imagine where the team would be without him.
Epps/Sincere both exceeding expectations. They're freshman, and I expect some mistakes and inconsistencies, but have earned their spots in the rotation. Epps is another player that has me wondering where the team would be without him. He has the presence to lead a team late game, and is one of the better FT shooters on a team that's below avg.
Mayer has single handedly won or kept the team in several games
TSJ is just plain fun to watch. NBA athleticism all day. Closest thing we have to an Ayo. You need a guy who's fearless in attacking and can poke guys in foul trouble. Epps has surprised me a bit--but TSJ is in your face and able to do it at a high level.
I had always assumed that even if the team struggles during the season, they'd be dangerous come March. But the flaws haven't improved much, and the ceiling, IMHO is lower than was hyped. All that said, I wouldn't be too surprised if they get on a run. The ceiling might not be as high as I originally thought, but they still have stretches where they can play with almost anyone, and as the season ticks away, I could see some things getting cleaned up.
