Depends on how he plays next year but if I had to offer an extension (based on right now) beyond that I'd offer something around 4 years and between 15-17 per with a backend TO worth 2 mil more than his final year. I could get on board with a 4/66 - 15, 16, 17, 18 with a TO for 20 at age 27. But again, so much depends on his development between now and next summer. That's the unfortunate part of the situation, typically teams have sufficient time on the rookie deal to find out a players worth before making any kind of commitment. With Fultz that time was cut in half.
