NFL's final four

t's down to four in the National Football League, with storylines aplenty.

Ageless wonder Brett Favre and his Minnesota Vikings meet Drew Brees and the mighty New Orleans Saints in the NFC championship, while another grizzled veteran in Peyton Manning leads his Indianapolis Colts into the AFC championship against the upstart New York Jets, led by rookie quarterback Mark Sanchez.

There is a little something for everyone in this Sunday doubleheader.

You've got a meeting of powerhouses between the Vikings and Saints.

Minnesota was 12-4 on the season, having lost its final four games, while New Orleans, which flirted with perfection nearly all season, finished the campaign at 13-3.

In this matchup, it's hard to determine the sentimental favourite.

Neither team has won a Super Bowl. In fact, the Saints have never even played in the big game.

For Minnesota, there's the Favre factor. It's hard not to root for the man many have been writing off as well past his prime for years.
