Blake Griffin officially agrees to five-year contract extension with Clippers Blake Griffin signed a five-year contract extension with the Clippers on Tuesday night that could be worth up to $95 million. The deal could keep Griffin, who has an opt-out clause after the fourth year of the extension, in a Clippers uniform until 2018. Griffin signed the contract in Las Vegas, where he was training with the U.S. basketball team in preparation for the London Olympics. Clippers President Andy Roeser and director of player personnel Gary Sacks flew from Los Angeles to Las Vegas to get their All-Star power forward signed. Griffin skipped practice with the USA team on Monday to fly to L.A. to take a physical, but he returned to Las Vegas and was back at practice Tuesday. Griffin, who will make $7.2 million next season, will make the maximum if he is voted to start in two All-Star games. Under the new collective bargaining agreement, players coming off their rookie-scale contract are eligible to sign for 30% of the salary cap if voted to start in two All-Star games, are named to an All-NBA team twice or are named the most valuable player. Also, every team is allowed one "designated player" who can get a five-year maximum extension on his rookie contract. Tim Duncan will sign a three-year contract to stay with the San Antonio Spurs, Yahoo Sports reported. Duncan's representatives and the Spurs are finalizing a few items in the contract, according to the report, but the structure has been agreed upon. Duncan, 36, declared himself "a Spur for life" during the Western Conference finals. He averaged 15.4 points and nine rebounds last season. Rashard Lewis has decided to join the Miami Heat, becoming yet another shooting option for the reigning NBA champions. Agent Tony Dutt said the free-agent forward and the Heat agreed to terms on Tuesday, and Lewis is expected to sign his contract Wednesday in Miami. A person familiar with the decision says the Golden State Warriors have agreed to trade starting small forward Dorell Wright to the Philadelphia 76ers for the rights to a player currently in Europe. Joe Paterno's family says the late Penn State football coach didn't cover up for convicted child molester Jerry Sandusky, and didn't act to prevent a proper investigation of the retired defensive coordinator. Paterno's family also called Sandusky a "master deceiver" in the statement released Tuesday after former FBI director Louis Freeh announced he would release the findings of his investigation into the scandal Thursday. Freeh was hired to investigate by the Penn State trustees, who ousted Paterno days after Sandusky was arrested in November. Paterno's family said the Freeh team declined its offer to respond to recent news leaks after the family asked to review the findings. They said Paterno never got a chance to present his case before he died of lung cancer in January.
