A lot of people say Kader is 'sponsor hopping' or whatever, but I don't hear those people question why the sponsors aren't able to keep him. He's doing well with his career overall, so I assume the sponsorship changes are motivated by moving brands for a bigger cheque. If I had to guess, I would imagine that Emerica was paying him in shoes and high fives, Vans probably offered a similar arrangement (if the stories are true about their humongous pro-flow team where nobody is getting paid), and maybe Nike is actually paying him well. If that's what happened, he's doing exactly what he should be. To me, the real question is 'why didn't Vans put up the money to keep him around?' Kader is 'in his window' right now, and he should get all the money he can while he's young, healthy, and marketable. He doesn't owe anything to Vans or Indy or whoever.
