Fans usually expect their team to win every game and when their favorite team loses, it can’t be because the other team just made a few more plays than their team did. They can’t believe that it’s even possible that the other team is good too and has good coaches and good players.
I always laugh how many times when a play works fans say, “Great call”, and when a play is a disaster, it’s a “terrible call”. As if all plays‘ success hangs on the actual decision to run a particular play not how well the players execute the play.
Put it more succinctly- most fans can’t believe their team can play hard and still get beat. It has to be that our players and coaches just didn’t play well, or they all suck, or that the refs screwed us…..etc. etc
