Sunday Countdown: Eli, Peyton and more

Sunday NFL Countdown airs from 10 a.m. to 1 p.m. ET on ESPN. Here are some of the features you can see this week.

Moving forward: Kyle Williams knew fans would be critical when his two fumbles in the NFC Championship Game cost the 49ers a trip to the Super Bowl, but death threats on Twitter? It took a letter from a 7-year-old fan to give Williams the proper perspective to put his mistakes in the rearview mirror.

Legends in new places: Peyton Manning spent 14 seasons in Indianapolis. Now he’s a member of the Denver Broncos. Ed Werder sat down with three quarterbacks who have similar stories. Joe Namath, Brett Favre and Joe Montana all won Super Bowls for their longtime organizations, then finished their careers with other teams. Namath, Montana and Favre share their experiences and tell us some of the things Manning may go through as he begins his time in Denver.

Mayne Event: Despite winning two Super Bowls in the past five years, Giants quarterback Eli Manning isn’t even the most popular quarterback in New York City. So there’s no doubt when the Giants held training camp over the summer in Albany, N.Y., he’d be the toast of the town, right? Wrong! Kenny Manye heads upstate to investigate in this week’s Mayne Event.

Eye in the Sky: For the first time in NFL history, five rookie quarterbacks will lead their respective teams Week 1. Ron Jaworski breaks them all down in our newest segment, Eye in the Sky.
