re: Do fans seriously cry over football?

Hasn't happened to me with a college (LSU) game yet; when I was young (80's) it was a badge of honor for LSU to play an elite team to the wire, even if they lost.

Pro's (Saints):
going back to early 80's, the Saints would have made the playoffs for the first time ever if they beat the Rams in the final game. Had a late lead, Rams trying to get into FG range, Vince Ferragamo floated a duck that Johnnie Poe could have fair-caught like a punt. Poe dropped it
Next pass got them inside the 30, and they made the kick.
I cried.

Saints vs Minnesota 2017, I was just stunned by the last second loss, shook my head and laughed at the absurdity. My son lost his mind and was about to break most of the living room furniture, and when I told him "hey settle down" I thought he was going to kill me for a moment. Definitely tears in his eyes.

Luckily, I was working last year when the no-call happened.

It's a tradeoff; if you're too cool or mature, or whatever, to cry over a loss, then you're not going to get the same magnitude of joy with a win.
