I say look at it this way
Rondo/Eddie/Lester
Ray/Marquis/Giddens/Tony
Pierce/Walker
KG/Baby/Scal/Williams
Perk/Rasheed
That is really our depth chart be position. For that reason with Tony and Walker out, the depth chart becomes:
Rondo/Eddie/Lester
Ray/Marquis/Giddens
Pierce
KG/Baby/Scal/Williams
Perk/Rasheed
I just don't see the team activating Hudson over Giddens as Scal and Giddens, even though they would be playing slightly out of position, are the only back ups for Pierce that aren't already playing larger roles elsewhere.
I think Lester sits to have more depth at the forward positions as the C's can literally have Pierce or Daniels play a point forward position with Rondo off the floor or can have Ray or Eddie bring the ball up and initiate the offense. Lester is a luxury at this point and will be shipped to the NBDL with Walker and Giddens once the NBDL opens.
