Some folks like to say it doesn't matter who beat you, and to them I say BOOOOLLLLSHYOUKNOWWHAT.
I take you to the sport of boxing. Who you beat, and who beats you, matters. If you are run of the mill, it comes out in the wash.
I will even take you to the sport of college football. Who you beat, and who beats you, matters.
Even in this league. Losing to some really good teams sucks, but it can help give you a measure of yourself and what to expect moving forward. We damn near beat the mighty Broncos and almost beat the Chiefs. It lets me know this team can compete with the best teams, and if they can take a step forward in some areas, beat them.
