The Knicks will be able to retain Jeremy Lin for the foreseeable future via the "Gilbert Arenas rule," according to CBS' Ken Berger. Lin will be a restricted free agent after this season and the Knicks are up against the cap thanks to the salaries of Carmelo Anthony, Amare Stoudemire and Tyson Chandler. But they can still retain Lin by using their mid-level exception for next season to match or exceed any offer sheets their new point guard gets. Lin is locked in.
