DEERFIELD, Ill. — Chicago Bulls injured point guard Derrick Rose was surprised when he found out by media members about coach Tom Thibodeau’s multi-year contract extension on Monday at Bulls Media Day.

“What?” Rose asked happily perplexed.

Bulls general manager Gar Forman announced Thibodeau had agreed to a four-year deal but did not go over the parameters of the agreement. When asked to iron out some of the details on the contract, Forman kept if brief.

Thibodeau, the 2011 Coach of the Year in his first season with the Bulls and runner-up last season, won 100 games faster than any coach in NBA history. He was previously an assistant with the Boston Celtics under coach Doc Rivers, helping the team win a championship in 2008.

“Well I’d like to be here forever,” Thibodeau said of his new contract with the Bulls. “Obviously, I’m glad we got the contract part done. I’m looking forward to the challenge ahead. My expectations are always the same. I’m very thankful to (owner) Jerry (Reinsdorf), John … [For more on Coach Tom Thibodeau signs multi-year deal with Bulls, click here.]
