As long as the Chiefs are there I'm good. I'm not someone who hates the Patriots, but it's become boring at this point. I'm really not interested in seeing Brady "further cement" his claim as the best QB, even that has been done multiple times. Also don't care that much about a Brady vs. Brees matchup.
Chiefs are legitimately one of the most entertaining teams I've ever seen. Would love to see Mahomes and co. in the Super Bowl.
As for the Saints or Rams, I think the Saints are a more entertaining team, and it may be a more entertaining Super Bowl if it was Chiefs vs. Saints, but I absolutely despise that organization. Nobody I dislike more than Sean Payton, and being a Vikings fan, their history over the last 10 years has made me hate them.
I think the ridiculous Chiefs vs. Rams game makes it intriguing enough to highly anticipate a rematch.
