The Raiders have shelled out hundreds of millions of dollars in the last two days under the belief they didn't have Crosby's salary on the books.
With the knowledge he's got to pass a physical anyway, I don't see why you don't see what the cost would be. Is it that crazy to think you might get him for less than a 1st round pick now? They almost have to get rid of him in the next 20ish hours, and a lot of teams have already gone in a different direction with their money.
