Peyton and Eli Manning may be two-time Super Bowl champions and future Hall of Famers, but at the end of the day, they’re still just brothers, and all brothers have a love-hate relationship.

In a sneak peak of NFL Film’s new “The Timeline” episode, which will center around Peyton and the work that went in behind his record-breaking 2013 season, we catch a glimpse into the “hate” part of Eli and Peyton’s relationship.

The entire documentary will air this Sunday on NBC, and you’re going to want to make sure you’re watching, whether your a Broncos fan or not.

Manning’s 2013 season was historic not only because of the touchdowns and yards, but because of what he had to overcome to get there.
