1. I had no idea that Tate was in the NBA, so good for him. 
2. He always played hard at Ohio State and I’m speculating that Harden may have taken issue with tough defense at practice. 

Charania reported Harden has had "multiple verbal confrontations with teammates in practice on Sunday and Monday," including throwing a ball at teammate Jae'Sean Tate after a heated exchange.
