I won't blame this whole thing entirely on Karl, but for everyone defending him, have you seen the games? I certainly haven't seen all of them, but from what i have seen, there are a lot of things that seem painfully off that i perceive to be a direct result of Karl
-Not playing to guys strengths: Cus shooting 3's, Rudy playing ISO ball AND power forward, Marco having to become a playmaker instead of hitting open shots off of well set screens, not speeding up the game and letting guys like WCS run during the games when Cuz was out, etc etc. Bottom line is, we have talented players, and Karl seems to be trying to make guys into player that they're not
-Defense: Maybe this isn't entirely on Karl, but the guys clearly look confused on D. This probably has something to do with effort and intensity, but our defensive set's just don't seem to be working, and as we saw last year under Malone, these guys CAN defend. Hell, the roster has changed a bit but Cuz, Koufos, and WCS vs Cuz, JT, Reggie Evans....how is it even possible that the D has regressed with such massive upgrades? My guess is that it's less about the players and more about the schemes, which is on Karl
To me, those appear to be the most blatant issues, and anyone who thinks that this mess is not on Karl and the team needs more time to "gel" is just plain blind. If it was about gelling, then we'd have some consistent lineups by now, not Acy starting...in fact, Acy starting should prove a point right there that Karl has to get his head out of his a**.
Bottom line - play to the strength of your roster, quit trying to make guys into player's they're not. That is on Karl
