So how much does Tanaka get? Between posting and the aav of his deal Darvish got $18.6 mil. People are saying Darvish is slightly better. I realize the situation with posting changes things a bit but I'm struggling to see this go over $20 mil aav if you include the posting fee. Something like 6 years $100 mil + the $20 mil posting fee seems right to me.
However, I have seen others on cubs den comments talking $150 over 6 years plus the $20 mil fee. If you figure $7 mil per win in FA which is the rough estimate that means he'd have to produce 24.25 WAR over the life of the deal or roughly 4 WAR a season. Only 11 pitchers have done that over the past 3 years Verlander, Kershaw, Hernandez, Lee, Sabathia, Scherzer, Sanchez, Price, Fister, Hamels, and Shields. That's basically assuming he's an ace when I'm hearing most view him solidly as a 2 with the potential to be an ace. My suggestion for 6 years for a total of $120 mil would be around 3 WAR/season which over the past 3 years 30 pitchers have done.
Perhaps I'm being too logical here and this turns into a feeding frenzy type situation. But, if it goes over $23 AAV for the deal it seems like the teams are setting themselves up for failure. I think the max you can go is 7 years $140 mil + the $20 mil posting fee even for the cubs who may feel over paying is worth it. At that price you're basically expecting him to be a 3.25 WAR player/season which over the past 3 seasons would have put him as a top 20 pitcher in the league. It would put him on the same level as Wainright, Latos and Zimmerman.
