I mean, I think its worth mulling over in Jose's case, and $35M should be the max. Also note that no other QO recipient has actually officially rejected yet, either.
At 3/$35M, Jose is effective agreeing to a 2 year extension at $17.2M ($8.6M per in 21 and 22) in addition to the $17.8M QO. I don't think its outrageous for him to think he can beat $8.6M AAV in 21 and 22. If the offer is closer to 3/$30M, then its 2 years $6M per....even more reason for Jose to "mull it over".
