Certainly a sign of bad and suspicious character.
Around here it isn't natural to not be interested in two or three teams as a minimum. Passing knowledge of several state/local/ professional teams is certainly a must, as from time to time you will be called on to join in a good cussing of them when they do something dumb. You can give a convincing performance if you don't know some names!
------------------------------------------ The folks in NE Ohio can commensurate with your group.
As a kid the Cleveland Browns were my team.
Otto Graham was quarterback and for ten (10) years from '46 thru '56, was a time when the Browns WON and then "Otts" retired.
Starting in '57, the Browns didn't win any more except in '64.
1960 and Art Modell comes to town and buys the Browns with other peoples money. 1964 and Paul Brown (The team was named after him) is gone as coach and the Browns win the championship.Fast forward to the '90s when carpetbagger Model moves to Baltimore.
During those 40+ years, the only winner was Model, not the Browns.
Home games were played in Municipal Stadium, with 80,000+ seating capacity.
Season ticket holders had every seat between the 30 yard lines.
Sell out crowds were standard.
Being a winning team was not.
Loge boxes were added, but limited.
Cleveland knocks down Municipal Stadium and builds a new stadium on the old site with lots of loge boxes.
Cleveland gets a replacement team.
It's not a winner either.
During football season, the TV sports programs spend all week crying in their beer.
If you are a sports fan in NE Ohio, ya gotta be tough.
