There's nothing better in sports than watching siblings try to beat each other's brains out.
Grudge matches like this are the kind of game we look forward to all year long.
The Manning brothers aren't the only ones who will have a chance to win a grudge match this year, either.
Though the schedule hasn't been released yet, we know which teams are slated to face off. With that in mind, here are the top grudge matches on the 2013 NFL schedule you don't want to miss.
Denver Broncos at New York Giants
Anyone who has siblings understands what a joy it is to defeat them.
It doesn't matter if you're competing to see who can slam down those nasty vegetables your mom served up the fastest, who can race up the stairs first or who can win an NFL football game—siblings love to compete.
This will be the third (and possibly final) time these two brothers will face one another in a regular-season game. Peyton has won both games to this point, but Eli has one more Super Bowl win to his credit.
There's a real chance these two could meet up once again in Super Bowl XLVIII, but in all likelihood, this will be the last time we'll see the Manning brothers go head-to-head.
If that wasn't compelling enough for you, it's worth noting that both teams are pretty darn good. This is a game you won't want to miss.
Minnesota Vikings at Seattle Seahawks
The Seahawks landed two former Vikings this offseason—both of whom left under less-than-ideal circumstances.
Percy Harvin couldn't stand playing in Minnesota. He eventually forced the franchise's hand and maneuvered for a trade, ending up in an ideal situation as a primary weapon for Russell Wilson—one of the best young quarterbacks in the NFL.
The other former Vikings star now wearing a Seahawks uniform is veteran cornerback Antoine Winfield, who is coming off one of the finest years in his stellar career. The Vikings unceremoniously released him, which was a surprise not only to him but to his coaches as well.
Minnesota attempted to re-sign Winfield, but he opted instead to take less money to play for Pete Carroll and the Seahawks.
You think he's got a chip on his shoulder?
This contest could well become a blowout, as the Seahawks feature one of the most stacked lineups of any team in the league. It's being played at CenturyLink field in front of the "12th man" and will be a difficult win for Minnesota.
That said, Adrian Peterson will have something to say about the outcome.
San Francisco 49ers at Seattle Seahawks
Jim Harbaugh and Pete Carroll have a long history of, shall we say, not exactly seeing eye to eye?
From their times at Stanford and USC to now, these two head coaches have a way of getting under each other's skin.
Just last year, Harbaugh and Carroll got into a little tiff when Harbaugh said Carroll's defensive backs played too rough against his receivers.
Aside from the fact that Harbaugh and Carroll provide us with unique and sometimes funny storylines, the two games between these two teams will provide enough drama without them.
Colin Kaepernick vs. Russell Wilson.
Frank Gore vs. Seattle's vaunted defense.
Marshawn Lynch vs. Patrick Willis and the 49ers' incredible front seven.
You won't want to miss these games, and at the least, you'll want to record them for later viewing if you can't watch them live.
