the not signing of green may be something as simple as the celtics' projection of him was wrong. which i can see based upon last year's performance.
for the celtics he averaged 11.4 minutes a game, 5.6 points, 35% from 3 point land, 3 rbs, and 0.3 assists. not awful, but nothing to rave about either. the celtics may very well have thought he is what he is and not worth resigning.
i don't think anyone, even green's fans, believed he would average over 17 pts a game in his first 7 games. he is averaging more points a game now than at anytime in his career. this is his best scoring and 3 point percentage year (50%) of his life.
heck. he didnt even start the year in the nba did he? no one expected this from him.
i understand how the celtics missed predicting this from green.
