Unfortunately in the US you have to look at what ever works to drive up sales. This is one way. Personally I will never watch hockey with my teen daughter because I can't handle it, but for teams that are struggling anything that will get butts in the seats, I am all for. At least here I only propose them half naked in baseball they were naked. You should have seen that Playgirl "Boys of Summer" spread.
By the way think of it this way. If you get 20 teen girls to drag there dads to 5 games and Dad gets hooked. Is dad now more likely to drag mom and his business associates? That translates into 100 new season ticket holders. In Vancouver and Toronto that isn't a big deal, in Nashville it is.
