Super Bowl 49 takes place this Sunday night at the University of Phoenix Stadium in Glendale, Arizona, which is where the Arizona Cardinals. The matchup will see the AFC Champion New England Patriots take on the defending champions and NFC winners the Seattle Seahawks. What's great about the game is that they were both the top seeds in their conferences heading into the playoffs. Seattle rode their home field advantage to another Super Bowl berth. It wasn't easy, though. After dispatching the Carolina Panthers easily in the divisional playoffs, they hosted the Green Bay Packers in the NFC Title game in Seattle. The Packers built up a 16-0 first half lead, then Seattle trailed 19-7 with four minutes remaining and were terrible on offense for most of the game. They managed to come back thanks to some big plays and a botched onside recovery by the Packers. In the end, Seattle QB Russell Wilson threw a perfect 35 yard TD pass to Jermain Kearse in overtime to win the game 28-22. If you ask a Packers fan about that game they'll probably be angry for the rest of their lives. The Patriots had a classic divisional playoff game against the Baltimore Ravens. The Ravens are a team that has given them major problems in the past. The Patriots ended up coming down from 14 points down to seize control of the game and went on to win 35-31. Their AFC Title game against the Indianapolis Colts was a laugher as the Patriots won 45-7 to earn their first Super Bowl berth since the 2011. Heading into Sunday night, the question is can the Seahawks repeat or will Bill Belichick and Tom Brady guide the Patriots to their 4th Super Bowl title. Whether you're a big fan or a casual viewer, here are seven things you need to know about Sunday's big game.
