We need his toughness.
We need his manhug before games.
We need his killer mentality.
We need his malice.
We need his defense and his threes.
Posey had a great mental impact on the Celtics when he was there and I feel like he would keep us focused and motivated throughout the season.
I don't care if his contract is terrible, we need him back.
(You are free to express your disagreement and to claim that I'm crazy - by the way it's 4:44 am here and the Celtics loss may have make me lost my mind

But, seriously, Posey is missed.
