"Although he wasn't on the conference call, it seemed Celtics president Danny Ainge overheard Paul Pierce express disappointment in the team's offseason moves, or lack thereof.

Ainge yesterday secured point guard Nate Robinson, once considered to be a poor fit in the Celtics system, to a two-year contract extension worth $9 million with performance bonuses, according to two NBA sources. Robinson generated little splash as a free agent, but a two-year deal provides stability after years of career uncertainty.

Considered a bust after being acquired from the Knicks along with Marcus Landry for J.R. Giddens, Eddie House, and Bill Walker in February, Robinson emerged in the postseason and was a capable backup to Rajon Rondo.

Despite watching Robinson struggle to grasp the defense and attempt ill-advised shots, Celtics coach Doc Rivers promised that the 5-foot-8-inch guard would help win a playoff game."
