About attendance and just for fun . . .
On an opportunity/urgency scale . . . it takes about 3 home basketball games (2.8) to equal 1 football game.
With 5 home games in football and 14 in basketball, it is easier to mentally put off attending a basketball game than it is to miss a football game.
It is easier to justify staying home for 7% of the season than it is to miss out on 20% of the season.
Football averaged 29,171 for about 145,855 on the season. Spread that out over 14 games and you get 10,418 per game.
Basketball averaged 3,675 per game, now if you take 2.8 games worth of attendance to get down to a 5 game season you have 10,290 a game. Probably 80% are the same fans but it could be said those 8% are more diehard basketball fans than any football fan, because I doubt 29,171 would be maintained if football had 14 home games, with games all over the calendar.
Now that is just one, there are a ton of ways to parse those numbers and yes in some ways they are apples and oranges but looking at the 2.8 games attendance total I can make the claim where right now basketball is garnering 38% of the interest that football is generating.
