Just a random theory, but hear me out
I think the sudden team switches are actually a tactic used by big brands like Nike and Adidas to sabotage other brands. I wouldn't be surprised if Nike paid Kader extra to announce he's on Nike with a random Strobeck video just as he has a colorway on Vans coming out, because it hurts them a bit more financially and image-wise. I think the situation was the same with Adidas stealing MJ off Lakai unannounced with a shoe coming out. They wanted him to sabotage Lakai on his way out.
