If the Skins did their homework and checked references, this would be no surprise. But if they did not check some kind of references, especially with the circumstances of his release from the Eagles being rather odd, then yes they should be taken back by this. In any business, no matter how talented an employee is, if that person cannot work with others they won't last. Sooner or later they become expendable. If DeSean has those kinds of issues, the best advice for him would be to work hard and keep the mouth shut.
