Since Monday, we’ve seen a plethora of NBA trades and free agent signings. While the biggest trade chip (Dwight Howard) remains in Orlando, the Nets re-signed center, Brook Lopez to a four-year, $60 million contract. While some may wonder why the Nets locked into this massive contract, consider that the Net had until Monday night to offer a contract to (and sign Lopez) before he became unrestricted free agent. With rumblings that the Charlotte Bobcats were interested, the Nets couldn’t take any chances. Under the new Collective Bargining Agreement, the Nets cannot trade any 2012 signed free-agents until January 15, 2013. Should the Nets trade for Dwight Howard, know that it can’t happen until then.

On the other side of town, the Knicks completed a sign-and-trade for old friend, Marcus Camby. Camby averaged 23 minutes per game last season, pulling in nine boards, five points and a block and a half. The 38-year-old Camby agreed to a three-year, $12 million contract and will backup Tyson Chandler. To land Camby, the Knicks had to surrender Toney Douglas, Jerome Jordan, Josh Harrellson, and two future second rounders. While it seems like a lot to give up for an older player, the Knicks know they have a three-year window to win now.

Finally, Jeremy Lin remains a free agent, but the Knicks are expected to match Houston’s offer sheet. The same goes for Kris Humphries and the Nets. The Nets are hopeful that they’ll be able to retain the Hump.
