SFO doesn't really want Kurt.
What they want is to force Arizona to pay to much for Kurt. They want the Cards to overspend and eat up more of their cap.
I have no problem switching to ML if Kurt wants too much. A top 6 salary is right around $10.2M per year. If he doesn't want to sign with that, use that $10 M to improve the team in other areas and begin the ML era.
I want several years of playoff football. I do not want to blow it all on another shot and then back to the basement. Follow the Steelers and NEP plan.
Also, that Matt Castle F-Tag value is bogus and should not be part of the negotiations.
