That's probably explains why NKE and Reeboks stock has been so weak in past few days. It sounds awful foolish to me but NKE has made this strategy work for years - signing phenoms before they hit it big. If Reebok signs Lebron they'll screw it up - might as well flush the money down the toilet.
I don't buy shoes endorsed by athletes - too expensive. I prefer New Balance which is quality shoe at a reasonable price.
