I don't think this should come down to who's better, Al or Josh (both are awesome players) or how many games each player in the roster have cost us. I for one rely on facts.
FACT: Smoove sometimes wins us games with long range jumpers (which he isn't supposed to shoot)
FACT: Smoove sometimes loses games because he keeps on shooting long range jumpers that won't fall (which he isn't supposed to shoot)
FACT: Last season, Smoove was way more productive, especially in the paint (where he's supposed to be)
FACT: Al doesn't wander around on offense, he tries to follow the game plan. You won't see Larry Drew complaining about Al settling for jumpers.
JJ and Jamal hurt the team a lot sometimes, but even they are doing what they're supposed to do. Maybe they shouldn't hog it so much, but isos are part of the offense. It's not difficult to notice who's going with the game plan and who isn't. Even when playing PF, Josh will shoot it instead of going inside. It's funny because now he's got a nice FT touch and won't use it anyway. He could be shooting 12+ FTs a game if he only were a bit smarter than he is now.
I really liked him last season, whenever he plays under control he's such a monster player. I was a huge fan of him. Not anymore. I believe most us 'haters' just grew tired of seeing the same crazy $h!t over and over again.
