Cavs All-Star guard Kyrie Irving is the only 2011 first-round pick to sign a contract extension so far this offseason. Tristan Thompson, Kemba Walker, Kawhi Leonard, Kenneth Faried, Reggie Jackson and Jimmy Butler, among others, could soon follow suit, but history indicates many of them will end up hitting free agency. Out of 295 first-round picks between 2001 and 2010, only 74 (25.08 percent) received extensions before their rookie contracts expired.

Other interesting nuggets from our research: 

- The curse of the No. 2 pick is alive and well: Only two players selected at No. 2 - Kevin Durant and LaMarcus Aldridge - signed extensions in the last decade. Derrick Williams was the second overall pick in 2011, so look for that trend to continue.

- Half the first-rounders of the highly acclaimed 2003 draft class received extensions while still on their rookie deals - including picks No. 27, 28 and 29. Darko Milicic was the lone Top 8 choice not to get one.

- If the Warriors sign Klay Thompson to an extension, he would become the first 11th pick in this century to get one before rookie deal ends.

- The Thunder (previously Sonics) have signed first-round picks to extensions six times in the last decade. That's tops in the league.

- New York and Charlotte have not signed a single first-round pick to an extension in the last 10 years.

- The Spurs are great at drafting, but pretty conservative with extensions: Veteran Tony Parker was the last player on a rookie deal to receive one from San Antonio.

- Only 17 players selected between No. 10 and 19 received early extensions compared to 20 among those chosen between No. 20 and 29.

- Greg Oden was the last No. 1 pick not extended. Previous one was Kwame Brown.
