this can't last

boozer played 27 minutes in a 105-86 loss to the celtics, dropping in just 10 points and finishing with a plus/minus of -20. meanwhile, millsap pulled down 13 boards in 23 minutes to go along with 9 points and a -5 rating (i.e., he played better defense). how much longer before millsap replaces boozer in the starting lineup for good?
