I don't remember Graham and Sasa ever on the court at the same time. I am pretty positive Billy and Ross were however.
A lot of our sets featured four guys around the perimeter with a post man working inside to get open, but I can't recall ever doing it with 4 guys that I would consider guards on the floor at the same time.
And I agree with you on Marshall taking Colella's minutes, but he did not look too bad to me either. High energy, seems to have enough quickness to play at this level, and looked fairly confident to me also. I was pleasantly surprised with him considering I had not really ever seen him before.
