I, for one, would go up to 3 years at the full MLE, and 4 years for something less than the full MLE (i.e., leave enough leftover to sign Walker using MLE money so we have him for 3 years in case he blows up).
But if the Celtics are still in the running with a 2-year MLE offer ($11.6 mil), my hope would be we eventually get Posey with a 4 year non-Bird deal ($17.25 mil) with a player option on the final season. Posey gets a longer term deal than he's being offered and he gets to stay in Boston where he is appreciated and competing for titles. The Cs would save about $3.5 million in the next two seasons - which turns into $7 mil since we'll have to pay the luxury tax this year and next - and keep its top six intact for next season and a chance at a repeat. And, if we really need it, we'll have the MLE available this year.
I thought a non-Bird deal would not be a possibility, and it still may not be, but with the way things are turning and the market drying up, it might be the best option for Posey. He mentioned before how nice it was to see how much the fans appreciated him here in Boston, compared to Miami, even though he was a bench player here behind three All Stars. That might make it easier and more likely for him to get local endorsement deals in Boston than in cities like New Orleans and Cleveland and LA (where nobody would know or care about him). Those won't make up the nearly $2 mil in salary differential, but it could help some.
