The Hawks' Johnson is on the Knicks' radar for 2010, assuming they can't get LeBron James.
Johnson, who will become a free agent in two summers, says he would consider being reunited with Mike D'Antoni in New York.
"You can't rule anybody out," said Johnson, who played for the Knicks coach in Phoenix. "At the end of the day it's a business. That's how you have to look at it."
