Heh, I'm not heartbroken about Mayo at all. He's an alright player who sometimes looks like he could be more but just hasn't.
Jeff Green is commonly referred to as a jack of all trades, master of none type player, which I find inaccurate since he's a jack of none, master of none but Mayo is that type. He doesn't have a stand out, elite skill but can shoot, pass and defend decently. Even his height falls under that heading since he's neither tall for his position or too small. His ballhandling on the other hand is not guard quality.
