I respond to your points below:
1. As others have pointed out, he had like 6 weeks from being a first time head coach to assembling a team for this year. Also he may not have realized at the time that we didn't have a tough group.
2. Maybe CKE said something about gimmick defense, but I can't find it. A search of posts shows that the phrase phrase "gimmick defense" in reference to vcu has been used on here long before English came along. Maybe some transference is going on.
4. I don't see 3 point shooting as our identity and I don't see CKE as inflexible. He likes the 3, but he has also said he likes 2 point layups even more. He studies the game and the stats and that is where the payoff is. He has just given the team the green light to shoot threes IF THEY ARE OPEN. I don't have an issue with that. Now, do you need to use mid range jumpers to keep the defense honest, maybe.
5. On the rotations, I think he had his rotation pretty set until it wasn't performing to his standards. There may be a little bit of revision of history going on here to say he didn't. His rotation was still pretty small and he still relied primarily on his starting 5 from the late non-conference schedule, but he needed people to spell the starters and he got Polite back from injury mid-season which would explain his mid-season insertion into the rotation.
6. I think you answered this point, somewhat, yourself. He isn't happy with the PG position. Also, I don't think he called Polite's number twice. I think he MAY have called it once, and the second time it appears that Polite called his own number.
