Well I don't have a crystal ball, so hard to know, but the point is, if we're only spending $14,6m on Marte there WILL be extra funds to make the team better. Who says we can't get Bregman, too? We currently have $26m in space before the first line. Another $20m before we hit the 2nd line. So $46m in total for a hard cap. Only spending $14.6 on Marte leaves a lot of room to still get a Bregman/another.
Who they'll go for is guess work, but as much as I really like Bo, I think we both assume that we aren't going the 7 x $30m it'll likely cost and that narrows your options considerably.
I don't even think we should trade Mayer for Marte, as in the way the roster is constructed. But if they demanded it (unlikely as they seem to be all about the pitching), I'd do it and work out the rest, because it's all well and good talking about the average 100 Mayer's v 100 Marte's (again don't disagree with the logic in general), we are close to being able to win now. So you make the move that helps you win now. For the next 2/3 years Marte likely helps you a lot more than Mayer. A lot more.
At some point we have to stop worrying about the future and try to win right now. We've lived in the future as fans for the past 6 years.
