Karaban is a guy who is smart and instinctual. Those type of guys tend to do better with similar types of players, which the team had in spades in the last two seasons.
Aside from McNeeley, who on UConn is a multi-level threat. The closest thing is Ball, but he isn't great at the rim. Spencer, Newton, Hawkins, Joey C. could all shoot lights out from 3 and all drive to the hoop. Sanogo and Clingan ate up space and added the 3 point shot (much more Sanogo though), but Clingan was a great passer.
On offense, Johnson, Reed, Diarra, Ross and Mahaney have underperformed or are pretty one dimensional. Ball at least has a midrange shot. The loss of McNeeley makes it really easy for teams to take away the things that Karaban does well. There have been times when they get mismatches and instead of dumping down low to Karaban (even Reed a few times) Diarra decides to try and take the big on the outside. For how great he is at defense and running in open floor, Diarra is awful at feeding the post. Reminds me of a few guys we had under Ollie who just threw it in with no thought or purpose (w/exeption of CV).
Also, I mentioned in another post. Hurley's and the staff's offense doesn't work if you don't actually constantly hit people with the screens. A few of the younger players show screen, but then fade and rarely ever body somebody. Karaban did a lot of the 'dirty' work. He looks to hit somebody and when floor opens up or guys turn their heads, he'll cut then. Some of these guys just go through the motions.
If we can get McNeeley back fully healthy and keep him healthy and Stewart continues to take the next step, which he appears he may be doing, the team will be fine. They need to realize they have a far less margin for error than the last few years and need to play a full 40 minutes every time out. Even yesterday, there was a play where AK rotated to Kalkbrenner, but neither Diarra or Reed dropped down from the double team/hedge after to the 3 point shooter. Kalkbrenner then found the guy for a wide open 3. If everyone pays attention to detail, and AK ends his shooting slump, this team could still be very dangerous.
