It took the Spurs two years to get him to play that well - he is a product of a dedicated organization that knows how to call out a player and help him. Mills is talented alright, but he wasn't focused or in a good enough shape until this season. Sure he had some seemingly breakout games with the Spurs and with the Trail Blazers, but it never materialized into a productive contribution. The Spurs called him out a year ago, and he responded well - they were sure to reap the fruits this season!
