I can see why it should go away, especially after the Mich/Wisky game. But for all the physicality in the NFL, when the final horn sounds, why are pro football players able to let the emotions of the game behind? Why can't other sports emulate this?
I think college and nfl football players and nhl hockey players are just glad they are not injured badly after a game, glad they are still standing. I have read and heard several times that going way back nfl players, when a game is not in doubt late in the 4th qtr, just say to each other on both sides let's just get this over with and nobody gets hurt.
And I am starting to change my mind that maybe the obligatory handshake line should go away and it should be like after a football game where players mingle with opponents they want to mingle with, guys they played against in high school and AAU, etc etc. Coaches can just wave at each other if need be.
college and nfl football do not have handshake lines but the players find opponents they want to congratulate or offer 'nice games' to.
A few years ago two nfl head coaches got into a pretty heated postgame dust up.
