CT,
They started Ron because he can bench press Matt Barnes with one arm:-))
Haha this is true
Second, there will be nights when JET and other of our older players get the night off. We have a TON of back to backs and I bet KG, PP, JET, etc. will not play in many of them. Therefore, your projected minutes chart works when everyone plays, but that is assuming everyone is healthy and suiting up every night.
I think it's mainly KG and Pierce that Doc is going to want to keep rested.
While Terry isn't young himself, he is in very good shape physically. Being an off guard and career 6th man, he doesn't take the same type of beating (or have the same type of mileage) on his body as PP and KG (who have played 30 MPG+ their whole careers, and have always played very physical).
Officially Terry is 35, but I think in terms of conditioning he's more like 32!
I think if we need to rest PP for a game we're still ok, because we can start Green at SF and both Lee and Joseph can play back up Green at that position.
Likewise if we need to rest Terry for a game we can easilly start Rondo + Lee and then Bradley and Dooling can provide backup minutes for both.
My bigger concern to be honest is KG. We don't really have a single big man who can rebound and defend the paint the way KG does - the closest we have to that is Fab Melo, and right now we have no idea how effective he's going to be. I guess if we had to rest KG a game we could start Wilcox and have Collins / Melo / Sully back him up, but it's not optimal.
I'd be much more confident if we had a guy like Ben Wallace who (if rotated with Wilcox) could very comfotably hold down the Center position in KG's absense on both ends of the floor.
The only real need I see for a guy like Barnes is against Miami, where it would give us yet another body to throw at Lebron on defense. I think we already have that covered pretty well though between Pierce, Green and Lee...but another to add to the list would never hurt.
