I heard from someone at Vans that he's not even on Nike, just didn't resign his Vans contract and kept pushing it back, now he's wearing Nike's everyday but doesn't have a deal with them even. Nike hasn't posted anything about him and doesn't follow him.
I'm sure they'll figure something out, but Nike just dropped a bunch of team, so it'd be a slap in their faces to drop loads of guys then just add Kader.
