FWIW, Drew Doughty was an 18 year old arrogant prick who didn’t think he needed to hit the gym. He toyed with the OHL his draft year because he was bored, and kinda under performed to his relative potential.
Once that got reigned in, we all know how the rest turned out. It’s a major reason why the culture brought about by guys like Greene and Stoll is so important to organizational success. It ain’t all points and highlight reel hits.
Sometimes, that arrogance is a good thing, when it can be controlled.
