Well he really barely played with these teammates his rookie season and he improved all this past season as the season went along, eventually clearly beating out for his minutes every other player Pop brought up to compete with him.
In his best games of the season he was involved in what the team was doing, as a playmaker or screener,but he wasn't in that series. Maybe the other bench veterans were so out of their own games and overwhelmed that they also got out of their offense.
Mills chucked jumpshots all series instead of running plays for others. It's a gripe of mine that Mills is not really a PG yet he had the ball a lot. For me it's on Pop. They didn't really involve him until game 6 when the game was out of hand anyways and Kyle ended up scoring a couple of difficult baskets over Roberson. We can't say for sure he wouldn't have helped when they didn't get him involved until the end. Hopefully that's not the case going forward bc Manu is in the very twilight.
