Newly signed free agent forward James Posey took his seat in between one of the Boston Celtics' owners and director of basketball operations Danny Ainge, and something that was very noticeable right away was the oversized NBA championship ring on his left hand.

"We're very happy Danny put this deal together and, obviously, from the weight on his hand he has championship experience," owner Steve Pagliuca said of the team's recent addition.

The Boston Celtics added another piece to what they hope is a championship-caliber team Monday, signing the 6-foot-8 free agent forward to a two-year deal. Posey will make between $7 and $7.5 million over the course of the deal, although the second season is a player option.

"I think he's one of the brightest spots this summer," Ainge said during a press conference to introduce Posey at the team's training complex. "He's a huge addition to our team. He's got incredible versatility on both ends of the court."
