An NFL source tells the Arizona Republic that the Cardinals are "exploring the possibility" of trading for Alex Smith.
Per the source, "no deal is in place." That means the Cardinals are not the team previously reported to have a deal effectively done with the Niners. The team was likely the Chiefs, but that doesn't mean San Francisco will stop shopping Smith ahead of the league's new year on March 12. By pitting teams against each other, they can maximize the haul they'll get for their backup quarterback.
