Drummond doesn't strike me as overly nice. He's just overly lackadaisical.
A guy with his talents in college, with the guards that he was working with, not to mention a guy with a skill set like Lamb had, should carry his team to a top 4 seed every single time. A dominant center in college is almost unstoppable, and he had the tools to be dominant.
I think it raises a big red flag that he couldn't do that. Honestly, how could he let his team lose to Providence? Who on PC could come close to stopping him?
