Football is my favorite, but basketball definitely has the most potential for growth because unlike football it has a playoff system. Another advantage it has is that you need a lot fewer players and have more games in which to prove yourself.
Selling out five home games at Cajun Field (31,000) is roughly the equivalent to selling out 12 basketball games (12,800).
What has to happen is for football to sell out consistently, go to bowl games, and get the ticket price up to the point that it can help subsidize the other sports. Football determines how much potential basketball has.
