He is the Comp.Avg. almost exactly. If I'm Arizona, I have four RFA deals on the table, with no room for any negotiation of any kind. Pick one:
1yr, 2.00, 2.00avg
2yr, 5.50, 2.25avg
3yr, 7.00, 2.33avg
4yr, 10.0, 2.50avg
If we want to buy back UFA, certainly he has a right to ask for more:
5yr, 14.5m, 2.9avg
6yr, 20.0m, 3.33av
yes it'll be more expensive if you buy his UFA years, i see him getting ~3.5M for a 6 year deal.
