I have no idea where you think one of the best players on their team is expendable. They hold the cards, all of them. They can workout a deal their comfortable with and if doesn't sign he plays under the restricted number. If some crazy team threw an unreal offer they can simply match, and when is the last time a team did that? The G-men once again hold all the cards!
When did I say I think he's expendable? I said in the New York Giants eyes, he is expendable which is fair based on their track record with wide receivers so they're not too ecstatic about spending the big bucks Cruz would demand. And Cruz is definitely worth an unreal offer.
