Plus, I think Pose has a couple years left in him and that is in keeping with the arc of this team as a whole.
This is my main worry, he hasn't looked good at all when I've watched New Orleans play. Now that's only been 5 or 6 games this season (and none recently) but I can't shake that he just looked old.
From what I've seen, Posey seemed more bored than old. He still is very focused on defense but he seems totally out of the offense... Whenever I see the Hornets play, I look at Posey on every possession. On defense he is still good, but he looks totally out of the offense, almost at a point where is standing behing the arc, watching what his teammates are going to do.
Against Indiana, Posey didn't touch the ball offensively or take a shot for like 10 minutes after he stepped on the court. He doesn't look an happy guy to me, and I think a comeback to Boston would reboost him.
He has probably declined a little bit too, but from what I've seen, his decline is more du to lack of interest/miscontent than age. His age decline would come in one or two years, while his contract would still be big, but that's a gamble I would take.
I agree that it would not be a good idea to kill our free agency opportunities this summer by taking Posey and his contract but our biggest chance of winning another championship is for this year, and getting Posey back would be a huge upgrade for this year (and also for the next one).
The future is just too uncertain for this team due to age and injuries. Plus we won't be the only team to be active in the free agency and we could very well lose our key "targets" to other contenders or teams willing to overpay them after failing at LeBron and friends.
