That seems a bit high to me. He has sacrificed for the good of the team, though, so that might be the cost of loyalty. That 4 yrs, $50 million was a fantastic deal. Having ,arguably, our best player making $12.5 million per is great value.
I'm hoping for $10-11 million a season. Preferably over 3 years but a 4 years, $45 million (with the 4th season partially guaranteed for 1/3 of his salary) would keep him under contract until the age of 36 and pay him more in the later part of his career than he probably could get on the open market.
