But that's why GM's get the big bucks. Porcello has done what he has done entering his Age 26 season. If you think he's going to put up his 2013 for the next 4 years, then $20M a year is going to be high. If you think his 2014 is the baseline, then $20M a year is going to be high-ish but reasonable. But if you project improvement - the sort of thing you expect from 26 year olds? (Remember Jason Varitek entered the majors as a 25 year old) Then $20M a year is absolutely his going rate and maybe even cheap. The Sox are projecting growth - and projecting growth from a 26 year old who is already a mid-rotation level starter, can lead to a good place.
