If he continues to play like has played this season sure, he is a bust. That said he is playing worse then last year so obviously something is up whether it's injury or slump. Time will tell.
Damn.. time hasn't told yet?
It's either what u said or he's nervous due to trade speculations.
But on Fields... he's nice, good IQ and court awareness, fundamentally sound, plays defense, looks for open shots and teammates but right now he's a role player in a position that demands or at least has the opportunity to be an impact player.
As good as he's been, to me he's a stop gap/fill-in type of player that doesn't make us worse but not exactly better (only due to minimized mistakes). At his position (SG) he needs to develop a scorers mentality and in this system that's great. not selfish but all around scoring. If he can do that then he instantly becomes more of an impact player.
