I tend to agree with him, I think the expectations for Jeff Green were too high.
The guy went from playing over 35 minutes a night to playing 10-20 at most, and people still expected him to be able to score 15 points off the bench every night. Even in the playoffs, in games where he hit some nice shots and played some decent 1 on 1 defense, people were quick to jump on him for every mistake. Any time one of the Big 3 sent a difficult pass his way that he fumbled, people immediately blamed Jeff, saying he's terrible.
I don't think Jeff will ever be a star, but he has all of the tools to be a very solid rotation player, even a starter someday. He just needs time to adjust, and I think, all things considered, he did a pretty good job for us this year.
I'll be extremely disappointed in Danny if he just lets Jeff go, though. The trade really would have been a major waste if all we got out of it is that Clippers pick and a rental of Jeff Green and Krstic for a few months.
No idea what he could be thinking with Pierce coming off the bench, though. Jeff starting and Pierce off the bench would seem silly. I don't know what SF he could possible trade for that would require Pierce off the bench, either.
