As we all know, it's tough to have so many good players, but I think that Giffey deserves more time. I agree that he is the most well-r0unded of the 3's and I think a case can be made that he is the best defender. It looked to me that he did the best job against Harkless when he was in, although he was quick to switch leaving Bazz to guard Harkless briefly a couple of times. He has quick hands and can be a very good passer. The pass he made to Lamb late in the game for the big dunk was perfectly timed and right on the money in a bang-bang play.
I think that there are multiple guys whose minutes will rise and fall with the competition this year. Roscoe is a great kid and he is the strongest and the best rebounder of the 3's, but he has not played well so far. He was called for fouls within 3 seconds of entering the game twice today. There will be games where he will be the best fit at the 3 or 4, but I agree with many that his best role is at the 4 when we need more speed and perimeter defense.
