I'm pretty sure Carmelo signed an extension this summer. Not as sure, but I thought Kaman did also?
EDIT: Yes on Carmelo, Kaman's in negotiations. Bosh also signed an extension this summer.

EL SEGUNDO – Clippers center Chris Kaman can obtain long-term security, and the Clippers can lock up one of the NBA's top emerging big men if the two sides can reach agreement on a five-year, $50million contract extension.
Coach Mike Dunleavy confirmed Monday that he made the offer to Kaman's agent, Rob Pelinka, with the backing of Clippers' owner Donald T. Sterling and vice president of basketball operations Elgin Baylor.
"Chris is a guy I'd like to see signed," Dunleavy said.
The NBA deadline for players signing an extension before the season is Oct.31. If that date passes without a deal in place, Kaman would become a restricted free agent at the end of the season. The Clippers still would be able to match any offer he signed with another team. Pelinka met last week with Clippers executive vice president Andy Roeser to work out a deal.
Bosh signed an extension, too.

The Raptors signed all-star forward Chris Bosh to a contract extension as expected Friday. The deal, which goes into affect at the beginning of 2007-08 season, is for three years plus a player option for the fourth, and would pay him nearly $65 million US over four years.
