Fwiw, I would agree that Miller had a good camp but he was rewarded for that- he played the first 15 games of the season. Heck, his first game of the year he was given 21 minutes. But he was -5 after just 3 games and did not look confident or sure of himself for most of the first half. The guy we're seeing now, looks confident!
Something has finally clicked for him these last 3 games and it's great to see. Fwiw, I'm a fan and I said before the season I thought he was going to breakout this year... let's hope he's really turned a corner mentally and that it's not just another flash point.
