Chiefs haven't been favored in San Diego since Dick Vermeil was head coach

Here's something amazing: After 109 games between each other, the Kansas City Chiefs and San Diego Chargers all-time series is tied. The Chiefs and Chargers have both won 54 games in the series and tied once. The 110th game on Sunday will break the series tie.

The first franchise meeting was in 1960 when the Chiefs were the Dallas Texas and the Chargers were the .... Los Angeles Chargers. (There's a clear joke in there but I won't take it)

The Chiefs and Chargers have been sweeping each other the past few years. The Chiefs swept San Diego in 2014 while the Chargers swept the Chiefs in 2014 and 2013. They split the season series in 2012 with The Phumble.

Three of the last four games have been decided by three points so it's fitting that Sunday's line is three points -- in favor of the Chiefs. The game is in San Diego, which made me wonder: When was the last time the Chiefs were road favorites in San Diego?

The answer: January 2, 2005.Trent Green, Larry Johnson and Tony Gonzalez were on the team. Doug Flutie was San Diego's quarterback!

From 2005 to 2014, the Chargers were favored by 5, 9, 12, 14.5, 13.5, 10, 14.5, 7,14.5 and 3 points. The Chargers had a seven-game home winning streak against KC until the Chiefs beat them last season.
