Sunday Countdown: AP, Coughlin, more

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

Also, check out our experts’ picks.

Peterson’s comeback: After 11 weeks, the NFL’s rushing leader is Adrian Peterson. Most seasons, this would not be news, but this is not just any season for Peterson. AP is coming off a torn ACL, and some questioned whether he had enough recovery time before taking the field. Those people were wrong. Cris Carter traveled to Minnesota to catch up with the best running back in the game, and got some insight into the leading candidate for the NFL’s Comeback Player of the Year.

Coach Coughlin’s important call: In 1991, Tom Coughlin was the head coach at Boston College. That year, his starting safety, Jay McGillis, was diagnosed with leukemia. Seven months later, he died. Even now, 20 years after McGillis’ passing, Coughlin calls Jay's mother, Pat, each Thanksgiving and Christmas, to talk about Jay’s legacy. This is the story of a long-standing commitment made by a Super Bowl-winning head coach.

When tight ends dunk: On Sunday afternoon, San Francisco meets New Orleans. One of the many matchups to watch is at tight end between Vernon Davis and Jimmy Graham. Both are coming off big games and both are threats to dunk after catching touchdowns. Graham is particularly adept at this skill. Davis? Not so much. We bring in one of our basketball gurus, Jalen Rose, a guy who knows a thing or two about dunking, to help uncover the mysteries behind the tight end dunking phenomenon around the NFL.

Peyton Manning soundtracks: Peyton Manning’s mastery of his craft shines through in this week’s soundtracks, taken from a recent victory during Denver’s current five-game winning streak. Hear what a Broncos win sounds like from the perspective of one of the best at his craft.

Mangini film room: It’s a powerhouse NFC showdown at the Meadowlands Sunday night, and who better to give you the X’s and O’s you need to know than Eric Mangini, who digs deep into his film room to uncover the keys for both sides in this playoff rematch.
