Jose is projected to make 16-20m in arbitrary, from what I have seen. This is a lot of money that could be added to a frontloaded contract for Machado or Harper.
Jose can produce at a slightly above average rate for a 1st baseman. The question is, is it worth it tendering him? Is the drop-off in production that Davidson and palka offer worth the money that can be spent on a superstar? Furthermore, Jose has been proven to be unreliable when it matters. The guy is about as unclutch as can be. He is getting a year older, and I doubt his defense gets any better (it probably gets even worse)
With his drop-off in stats last year, I wouldn't be surprised if he gets even worse. Do the Sox tender him or let him go and spend on Machado/Harper?
