I'm not watching the game but I was reading the thread and this stuff bugs me.
Willie WAS starting to put some of the pieces together. A mid range jumper here and there, that crazy gliding left-handed take to the hoop, blocking a shot on one end and running for the dunk on the other, getting easy dish offs for dunks, etc he was looking more comfortable but still having some rookie lapses.
Not firing Karl may have saved the franchise money but it has also likely stunted Cauley-Stein's growth and soured the locker room/team chemistry further.
