Super Bowl LII cheat sheet for newbies: Storylines to watch

So, you just heard there's a big game on Sunday? Read this before your party.

It's the underdogs vs. defending champions

Meanwhile, the Eagles have never won a Super Bowl. This will be their first appearance since 2005, when they lost to Brady and the Patriots.

Eagles Head Coach Doug Pederson said today that he has a lot of respect for the Patriots, but the team is staying focused. "It's about what we do," Pederson said, "Our guys don't read into what is written or said [about the dynasty] too much."

The Gronk factor

Gronk is a huge part of the Patriots' offense and would help the team's chances of defeating the Eagles' tough defense.

"It's always great to have him out there. He’s a great player, great person, great teammate and a big part of what we do," Brady said to reporters on Saturday. "So, it obviously hurts when he’s not out there for a lot of reasons, but he’s doing the best he can do and we’re all hopeful."

The Eagles keep flying

The Eagles have taken some hits this year with key players -- star quarterback Carson Wentz to left tackle Jason Peters -- landing on the injured report. Yet, the team keeps winning.

Defense, defense, defense

There's a belief in sports, defense wins championships. If you can’t score, you can’t win, right? If the Eagles can keep this game low-scoring, they have a shot. Brady himself has said that the Eagles defensive line is the best they have faced all year.
