It's so hackneyed these days for sports fans to conflate idiocy and "passion"/effort. You can play hard and bring toughness while still being not-a-moron. There are plenty of successful examples at all tiers... Shane Battier, Kawhi, I think Amen may be developing into such a leader, myriad others who don't get the toughness or effort credit they deserve. Playing dirty and yapping all game does not equal playing hard, nor does that make you some dirty dawg who always steps up. It makes you unstable. I don't think that's the only issue. I think his **** flinging also adds to his instability and is liable to give extra motivation to the other team. He has a penchant for waking sleeping giants.
