I agree with you. Samardzija is likely 5th on the list of FA pitching this year after Price, Greinke, Cueto and Zimmerman and above Kazmir, Leake, Happ, Gallardo and Fister. Shark's pitch selection was pretty suspect in 2015 relying way to much on his cutter. Teams are going to see that as easily fixed and will consider him a solid #3 that could outperform that. MOR pitchers make between $15-$19 mil. If it's years he wants I'd guess 5/$75 is close, if it's money somebody might go 3/$57 with options. Now looking at it from Samardzija's point of view, as a guy who has bet on himself, if it's years he wants he may very well accept a QO because he'd' be well paid at $16.5 and if he has a great year, gets the ERA back around 3.0, his WHIP around 1.1 and gets his K's back up he'll probably get that same 5 year offer but at more money next year. Say 5/$85. So from where he sits he has an opportunity to make $101 mil over 6 years if he accepts a QO. With what we know of his personality he just might do that. The question is can the Sox risk that? I say they can't with a rotation of Sale, Rodon, Quintana, Fulmer or Johnson and Danks. With what Johnson showed in September and the coming of Fulmer it's likely Shark would be one too many at the party, unless they were to deal Quintana. I'm guessing there's a lot of soul searching on that QO right about now.
To go along with that here's my best bets on what the top pitchers sign for (assuming Samardzija is not offered/does not accept the QO):
Price- 7/$230 and a team either front loads the deal or does a Sherzer type deferred deal.
Greinke- 6/$190-$200
Cueto- 7/$160
Zimmerman- 6/$120
Samardzija- 5/$75
Kazmir- 4/$60
Happ- 4/$55
