Is it okay to think the team needs at least one, but probably two young players in the starting lineup next to Rondo, and think that Ray should be one of the two current older veterans to shift to the bench?
I imagine that I'd keep Pierce and KG starting for sure, bring Ray off the bench, and alternate between Bass and JO starting depending on matchups, with Wilcox and Steimsma the 4th and 5th bigs in a 4-big rotation. I might consider a rest rotation, giving 1-3 games off to a player so that they all keep their timing/game conditioning. I guess that means I'm okay with Steimsma as 4th big...good deep big guy depth (way to go, Danny!)
I suppose Pietrus is the natural energy, guy, shooter, and veteran defensive pest to start on the wing next to Pierce. Work the ball through Rondo and Pierce, with Pietrus, Bass or JO, and KG as shooter/finishers. That's solid.
Then there aren't many 4th guard/backup PG minutes to spread between Dooling, Bradley, and Moore, so they can have a rest rotation, too. Lots of deep guard depth.
So Ray's right in the rotation, still as the 2nd guard in minutes (behind Rondo, IMO). Pietrus gets starter minutes, as he also backs up Pierce (still 3rd wing in 3-man rotation, but starting).
But really, it just makes the most sense for Ray to come off the bench, and it has nothing to do with any one game, streak, win, or loss.
