This article provide a good perspective on why Prescott turned down the offer - it makes sense to me.. I know Wentz is much better than Prescott but Prescott have data to support his decision, and to be honest, if I was Prescott and I see that I have data to support my wish then I will stick to it. Although, I doubt Prescott literally expects to get $40 m per year, it's just opening point for negotiations.
