Cornstein refused to disclose the amount of the contract, but it's believed to be worth between $60 million to $70 million, based on previous negotiations.
The signing came just one day before Dalembert was set to get on a plane and visit the Atlanta Hawks, who had the money under the cap to pay him a maximum five-year, $70 million offer.
Of the three top big men on the market, Dalembert was the center with the most upside. He has great range and is athletic, with great shot blocking instincts. He's shown he can be a volume rebounder and his offensive game is emerging. He was very inconsistent at times this season, but in the playoffs against the Detroit Pistons, he played the part of a franchise center.
The Sixers made a power move this offseason, firing head coach Jim O'Brien, who wasn't a Dalembert fan, and replacing him with Mo Cheeks, who is. Philly let it be known that O'Brien was fired, in part, because the Sixers are committed to Dalembert.
