I posted something tangential to this in a comment under one of Trueblood's articles but now that this is real I think it's worth thinking about more. If you want to read tea leaves on how confident the team is about extending Tucker, I think there's is a direct correlation between how much multi-year money the team adds from here and how likely it is that Tucker walks.
Tucker and some unlikely Shota option decisions aside, there is no money set to come off the books after this year besides Tucker. So if the team has real expectations of extending Tucker, they'll primarily stick to 1 year deals aside from Kelly (you always need a veteran backup at C). Reason being you want to to have some money to spend in addition to a Tucker deal. So like if Castillo or Flaherty is our next SP that's a bearish sign for an extension, while a guy in his walk year I take as a positive.
