hmmm...18.6. it would be great if we had a great defender we could put at the 4 in place of posey to tighten that up. oh wait...there is that garnett guy. he could play the 4 we just need a solid backup center for 15-20 minutes that can help keep kg at the 4, provide length, athleticism, block shots and finish down low. danny has his eye on chris andersen. i think thatll be fine. it keeps posey at the 3 where he belongs albeit as tim pointed out since he got half of his minutes at the 3 and those now wiped out were paying 6 mil for a guy thats gonna get not much more than 15 mpg when you add in giddens paul, ray, and whatever 3 danny might want to look at. hell if house is brought back he could get time at the 2 as well. doesnt look good for posey.
Posey provides far more to the Celtics in terms of experience, defense, and shooting than do Andersen, Giddens, or any other free agents available. I think it really is that simple. Without regard to individual match-ups, a team with Posey on the court is superior to a team with Andersen or Giddens at this point.
