Sounds pretty similar to the Rondo to Sac deal which was supposedly bringing back the #8, McLemore, and Thomas.
If people were on board with that one, I think they would be on board with this as we should still be able to pick up Randle, Stauskas, or Payton.
I don't know, though - I love Rondo and it is Ainge's job to surround him with more talent. If he can't, however, then it seems pretty reasonable. I like Lawson and Faried.
