I think Flip has improved, and it's difficult to tell if the pussy-ish rebounding effort this team gives regularly has anything to do with him or not. Does he practice and emphasize boxing out?
What I hate is his "take what the defense gives us" offensive philosophy. it's such a pussy-ish offense that is reliant on jump shots only. I don't think everything wrong is Flip's fault, but I think people (in particular Joe) over-estimated how much this team can "self-coach", at times we expect the players to do things that most players in this league don't do, things that are the job of a coach. I don't need a hardass, I just need someone with a strong offensive philosphy, who will help preach an inside-out offensive game, defense, and rebounding.
