Ray for Mayo alone i don't think makes sense or the C's (also it's impossible as pointed out) because it is a downgrade for this year, which is really our last hurrah. However, due to some of our other roster concerns, if Memphis really felt like they needed a vet SG, if you could snag Mayo, Darrel Arthur and Sam Young for Allen you'd have to think about it.
I would be all for a Ray for Mayo, Aurthur and Young(still would do the trade without young). Ray will be 37 next year and can't create his own shot anymore. We need young guys that can, and Mayo can do that. He is still very young and with Rondo I am confident he could become a more efficient scorer. Lets face it the C's will be lucky to make it past the 1st rd with their current roster .
We would probably have to send a PF back though in this trade because they were trying to trade Mayo for McRoberts. send them Bass and get a future pick maybe ?
Bos sends: Ray and Bass
Mem sends: OJ Mayo, Arthur, Young, Skinner(for salary match)
Now you have young Pieces in Mayo, Arthur ,Rondo and hopefully Bradley,JJJ or Etwuan develop into a player and the rebuilding process has begun .
