Not to backtrack but...
3. Where the fuck did you get the idea I want "salary caps" for skateboarders? The pros getting paid insane amounts of money are the ones gobbling corporate dick. Getting paid to live a decent life means you can survive and also have extra money to do what you want in your free time. If you want more money, work a side job, make art and sell it, or whatever else you want to do. But seeking out a sponsorship from a sporting goods company when you're a skateboarder is not the right thing to do.
Guy is 40+ years old at this point, if Nike can help him retire as a skateboarder and not have him get forced into a desk job to support himself and family (like many of these dudes probably do) for the remainder of his working life, that's pretty cool. But that's just my opinion, small skater owned board companies rule, but these shoe giants (vans, nike, cons, adidas) dominate the market. Plus you've got all these small companies paired up with shoe companies, all the 917 dudes are decked out in Nikes and the Polar dudes are all in CONS.
