The Kansas City Chiefs are 5-0 but they are still underdogs going into Sunday night's game against the New England Patriots. It seems a bit surprising because the Chiefs do have a perfect record and the Pats are only 3-2 ,but a closer look at the numbers shows that we should've expected this. According to ESPN via Pro Football Talk, Sunday's game will be the 56th game in a row where the Patriots are favored when Tom Brady starts.

This is an NFL record breaking Kurt Warner's mark where the Rams were favored in 55 straight games. Steve Young and Joe Montana have also at one point during their careers held the record.

When will streak end for Tom Brady, Patriots?

The big question now is when will Brady's consecutive games favored streak end. If the Patriots beat the Chiefs on Sunday, it's hard to imagine it ending any time soon. Maybe if a team like the Chiefs gain home-field advantage in the playoffs, it might finally be Kansas City that is favored over Brady and the Patriots.

If New England loses on Sunday, it could happen as early as next week in Chicago. The Chicago Bears have looked impressive this year, and if they blow out the Miami Dolphins this weekend combined with the Patriots losing to the Chiefs, maybe Brady's streak will end at 56.

Brady and New England aren't thinking about this though, they are only thinking about the tough battle they have ahead of them on Sunday night football, a game that can't be taken lightly given that there's a good chance they'll meet again in the postseason.
