But that's the thing there are people arguing for just a home jersey in a traditional style (much like the AFL) and minimal usage of away or event jerseys. So my question is if that is the case (and yes I am aware that long term sponsors are not common practice) how many jerseys get sold?
That's a good question. I don't have any figures for any of the sports leagues down here, but I know that back in Canada the top three teams in terms of merchandise revenue are the habs, leafs and riders. each of those teams has continuity in their uniforms, they're also insanely popular both in their markets and across country, saskatchewan accounts for 70% of all merchandise revenue in the CFL.
Below the 49th parallel and in baseball the Yanks and the Sawks are the highest earners in terms of merchandise revenue again both have continuity and both are extremely popular (isn't that right, espn?)
I have no problems with teams being innovative if you don't have a tradition and you don't have a winning legacy. if you can be innovative while looking good, you're bound to be a success when it comes to merchandise sales—you'll also be making people sales to people who aren't necessarily fans and an innovative design may sway the young fan who hasn't made up his or her mind about what team to cheer for and spend money on but make sure that today's innovation becomes tomorrow's tradition
The benefits of staying traditional include keeping local fans happy—players seem to prefer it, too. It keeps the overall look of the franchise consistent and it's easier to associate players of today with the players of yesterday.
