If we were able to resign Ray after a buyout, I'd think Eddie, TA and Baby would take their places behind the break in case of foul trouble, injury or other emergencies glass, while Perk would return to the 24 mpg he averaged during the championship season.
Rondo 36/Daniels 12
Miller 18/Ray 30
Pierce 36/Miller 12
KG 24/Jamison 24
Perk 24/Sheed 18/KG 6
Ray, Jamison and Sheed would sub in 1st for Miller, KG and Perk, then Miller and Daniels would swap for Rondo and Pierce. KG could sub in for Sheed when we want to go small and quick, before Perk returns for Jamison to re-establish a traditional line-up.
Using the championship line-up as reference, Daniels would be taking the Cassell role, Miller would be absorbing some of Ray's reduced role and taking Posey's back-up swing role, Jamison would be taking Posey's role as the small ball stretch 4 and the Powe role as the rebounding 4, and Sheed would settle into the PJ Brown long 5 role. Eddie, Baby and TA would reprise their bit roles.
