Steve Mills was hired by the team for that position on Thursday, sending former general manager Glen Grunwald to a role as an "advisor."
Grunwald held the position for only two seasons.
Houston spent the final nine seasons of his 12-year NBA career with the Knicks, and is second in franchise history in three-pointers made and attempted. He was appointed special assistant to former general manager and president Donnie Walsh in 2008.
More from the Bleacher Report:
When taking a step back and analyzing (Mills' hiring), it actually makes sense, especially if Allan is to eventually become the GM of the Knicks. By working under Glen for a couple of years now, Allan has been getting an inside look and education at the engineering approach to the mathematical side of making a team an economic success. "And now, with a few years as an understudy beneath Mills, it would appear that Allan will now get an inside look and education to becoming a true blue-blood sports business professional in New York. Steve has the track record and pedigree of a top sports executive in the current sports and entertainment market. With those two experiences to add to his resume, above and beyond his deep-rooted ties to the Knicks organization, I believe Allan will be primed to become the GM in New York."
