Not the first time that anecdote has been leaked. It's not uncommon for Alex to do that after he's struggled in a game. Probably a first for foul shooting though, usually 3 pointers.
My biggest concern for Alex is how he seems to be internalizing any perceived team/program "failures". After one of the Maui losses, he was in the presser saying it was all his fault and he had to fix it. More concerning than those ludicrous words, was his demeanor and body language. Tight lipped, tight posture. It made me actually worry for him personally. A guy like him has gotten to where he is by outworking people, and being a type A+ hoopster. Can work against you when there are struggles. "Every mans strength is every mans weakness". He needs to have the freedom to fail like everyone else, and unfortunately, he is the one that doesn't seem to give himself that luxury.
Best antidote for AK is a healthy Liam McNeeley to take some of the heat off Alex, even if it is self imposed.
