My only concern is the bench is not balanced. Assuming Perk gets healthy, you have two small-ish guards (Nate, DWest) backing up Rondo (a smallish guard who will play lots of minutes) and Ray. You have Daniels backing up Pierce. And then you have JO or Shaq, Perk, and BBD for bigs all of whom can be great compliments to KG, but I don't see another good pairing of bigs when KG is out.
For me it comes down to Daniels and Ray - if you are okay using them at SF, then Doc should be able to make things work - but it probably means West or Nate is going to get a lot less minutes then they'd like.
