you do understand that duce staley was cut, and that "base salary" only counts as a "cap hit" if you actually employ that player, right? i think youre confusing a players cap value with their cap hit. either that or you still think staley is on the roster.
since he was fired his base salary of $4,690,000 (for the 2 remaining) is out the door with him and all that remains is the $2,342,500 pro rated portion of his signing bonus, which is paid off in lump sum rather than being pro rated (as per league rules).
id say its still a pretty solid source if you understand what youre reading.
