I'm left with the impression Dallas just really never had any interest in doing a S&T with us. They probably figured it'd be in their own best interest to keep us away from guys like Mayo or Lee. Especially considering Dallas ended up with Mayo.
I still find it extremely difficult to believe Mayo would agree to a $4M 1 year contract (with a player option for year 2). The only explaination I can think of, is Mayo must think he'll be the starter, and with a good showing this season he'll cash in next year.
