Championship Sunday started off as expected, with the Patriots holding off the injury-riddled Chargers to advance to their fourth Super Bowl in seven years. The nightcap, however, was a major surprise. Led by Eli Manning, the Giants upset the heavily-favored Packers in sub-zero temperatures at Lambeau Field. Manning was owned by just 22.4 percent of Gridiron Playoff Challenge players, and only one other Giant ranks in the top 10 in terms of highest ownership percentage. Oddly, that player is kicker Lawrence Tynes (25.1 percent), who missed two potential game-winning field goals before finally putting the winner through the uprights in overtime.

The Gridiron Playoff Challenge is now locked, so there's nothing left to do but sit back and enjoy the big game, which is a rematch of the Week 17 classic between the Patriots and Giants. Tom Brady (54.1 percent) threw two touchdown passes to Randy Moss (25.2 percent) in Week 17, but Moss has been shackled in two playoff games. Manning threw four touchdown passes against the Pats, with Plaxico Burress (13.4 percent) pulling in two of the scores. Check back after the Super Bowl for final standings, and thanks for playing the Gridiron Challenge.
