Shumpert needs to stop acting like he's Gary Payton and show some humbleness in his rookie season!
His body language is terrible for a rook who hasn't done anything yet, walking around like he owns the league and is the second come of D-Wade or the Glove.
What about starting to actually convert some dunks instead of rimming them Shump? In this league you better deliver FIRST before you start bragging.
Blame D'Antoni for it he gives the players way too much freedom, an overconfident young man like Shumpert needs an old school coach like Popovich who gets in his head and rebuilds him mentally (like he did with Parker in his rookie season).
