I just saw a replay of that Memphis game, and Robert looked the best I've seen him. He's filling out, stronger, faster and is quite a good passer. Looked like a leader on the court. He looks like he will play significant minutes this year. I still think he's setting too many picks outside, and leaving himself out of position for a rebound. But that's their style.
Perhaps having him and Tacko in the game at once might result in one of them playing closer to the basket, and one back to cover for defense. I noticed Ainge sat next to Tacko a good part of the 2nd half. Both he and Robert had their best games so far. Both shot 75%, and you can't beat that with 3P shooting. You have to create offense for guys who can get easy shots like that.
