I would have traded Forbes for a second round pick earlier in the season. He's just plain old playing better in the last month, and earning the grades.
Bryn put in a lot of work in the weight room in the offseason, and it showed. He's a little heavier, and definitely stronger than he was. I re-watched a couple of the games from early in the season, and a couple of the recent ones, just keying on him. I think it just took him that long to figure out how to use the extra size and strength to his advantage.
In fairness to D-Mo. You've got a guy fighting to work his way back into the NBA. He's getting 4-5 minutes. It's sort of natural to press, trying to impress. I don't know about those nasty shots, but the fouls are probably more him trying to get notice for his D. Tough situation.
