Knicks president Donnie Walsh will learn his true fate with the team before the 2010-11 season comes to a close. Walsh's four-year contract with New York includes a clause designating March 31, 2011, as the day the team must decide whether it will pick up the option on his fourth year, according to a league source. The Knicks will be some 70 games into the 2010-11 season at that point. Walsh's future in New York became cloudy when the Knicks re-hired Isiah Thomas late last week. http://espn.go.com/blog/new-york/knicks/post/_/id/258/dolan-must-decide-on-walshs-future-by-april-1
