I know there was a lot of criticism of Vonleh starting, but I even think that was a good move. It made Vonleh more comfortable and helped his development. After a few months of starting, he doesn't have any jitters when entering the game. He's used to playing against NBA starters, so when he enters the game against reserves, he's calm and confident in his ability to play at this level. That's significant progress for a 20-year old.
It also made Harkless hungry. He's a young guy that wants to make his mark, but didn't always bring his A game earlier in the year. His effort night to night was very inconsistent. Since the all-star break, he has gone from being out of the rotation to being a key reserve to being a starter - and he's earned it and is playing much better and bringing much more consistent effort on a nightly basis. If he would have been gifted the starting role and training camp, I don't think he'd be nearly as productive and consistent as he is now.
