Free agent Donovan McNabb would reportedly consider a return to the NFL "if the right team called." CBS Sports' Jason LaCanfora suggests the Cardinals and 49ers as potential landing spots. Even though McNabb lives in Arizona, the team has never shown interest. The Niners have no need for his services. Rotoworld heard from a reliable source last month that McNabb had ballooned well beyond his playing weight this summer. It's hard to imagine him playing meaningful snaps for any team in 2012.
