I think the backup SG in the playoffs will be some combination of Delonte West, Paul Pierce, and Jeff Green. I doubt that either Wafer or Pavlovic sees a lot of time.
Yes. People forget that each position only has 48 minutes of available time at it. If Jeff Green were to only backup Paul Pierce, he'd likely be limited to 12 mpg. The only way to get him extra minutes is to slide people around. While we may seem him at the 4 a little bit, the fact of the matter is that if we do that, it's going to be tough to find Baby minutes, who should see less time at the 5 with (hopefully) two healthy O'Neals and Krstic.
So that pretty much only leaves the option of swinging PP down to the 2 (thus eating up practically all the backup 2 minutes behind Ray) to give Green somewhere around 25 mpg.
And while that's unfortunate for Wafer, I think we'd all agree that 10-15 extra minutes of Jeff Green on the floor is a net gain over Wafer.
And thus, I don't see any time for Arroyo, since West is going to have to get most (if not all) of his minutes at the backup 1.
