At one time I was rather assured that their value would each be at around $3 million per season on no more than a 3 year deal, but with the way other teams are shaping up, I want to make as strong a punch as I could over the next two years, then clear the decks. So I'd overpay to keep both of their contracts to 2 years, but might consider longer for Nate if he took a discount...
But anyway, I'd pay either a high sum to line up their contracts to Ray, KG, and JO and make the strongest 2-year push I could. Keeping both of them would help create the strongest possible roster for the next two years.
