While the Knicks pursue Steve Nash as their point guard of the future, it is possible they could lose both Jeremy Lin and Landry Fields to free agency. As has been widely reported, Lin will meet Wednesday with the Houston Rockets and Fields has been extended a $20-million offer sheet from the Toronto Raptors. The Knicks would need to come up with about $9-10 million annually in order to entice Nash with a three-year deal, meaning parting with some combination of Toney Douglas ($2 million), Dan Gadzuric ($1.3 million), Jerome Jordan ($762,000) andJosh Harrellson ($762,000).
