Jim Todd and Darrell Walker have joined Mike Woodson’s staff as assistant coaches with the Knicks.

Todd is reunited with Woodson, after serving as an assistant coach in Atlanta from 2008-10, and then most recently, served as an assistant coach with the Sacramento Kings this season (2011-12).

Walker brings more than a decade of coaching experience to the Knicks, having served as both an NBA assistant coach and an NBA head coach. He was most recently an assistant coach with the Detroit Pistons (2007-08 through 2009-10).

The Kings have hired Clifford Ray to work with the team's big men.

Ray began coaching with the Mavericks in 1987 and was most recently an assistant with Boston from 2006 until 2010.

"He just has a way of talking and communicating with bigs who perform like a five-man," Keith Smart said.

"I've seen all the guys that I've had, big guys that he's worked with, how they developed and developed mentally, how they developed to understand the game from the five position," Smart said. "That's really good teaching that our guys need to understand."
