Kudos to Horatio for not blaming his poor play mostly on injuries like Bobby C and others. Newsflash though, great players play well in any system. Sure, there are styles to suit different players, but our style isn't the reason Malik didn't have the ball handling to get by average college defenders and score around the rim or find the open shooter.
Bottom line is that Malik wants to play PG because that's what 6-3 185lb guys play in the NBA if they are really successful and more than just role players. He's got it in his head that he will be a star in the League, so that's what he's worried about. Better for all if he goes somewhere that is willing to put Malik before the team.
