Watch this video of Peyton Manning and Kenny Chesney 'performing' at Sloppy Joe's in Key West and get back to me on whether Peyton's wife has any reason to be concerned.Between Tom Brady and his 'great fashion sense' and Peyton singing duets with a guy who obviously has a mancrush on him, who's a kid to look up to these days from the NFL ranks? Oh, Jim McMahon, whereforartthou? Eh, at least Tom is ...more.
