That is a mischaracterization. MLBTR said "Of all the teams in the mix, the Twins’ payroll outlook is by far the most open (zero dollars on the books beyond the 2019 season)":
The Cubs are not against any luxury tax, and absolutely have the financial flexibility to sign Darvish if they want to. As could the mystery team, if it wasn't the Dodgers. And while the Astros might prefer not to, hence kicking the tires on Cole, they too have the flexibility to do it if they want. (Rangers are likely in that group too -- any inflexibility would appear to be self-imposed, which frankly might apply to the Twins as well.)
Rumors... Just Rumors... But Rumors suggest the mystery team is the Dodgers.
The Dodgers... I really believe the Dodgers are trying to reset that Tax penalty. Or else that Braves Trade makes less sense. So... The Dodgers would have to find a taker for Kemp and that isn't likely. OR trade Puig and another fairly costly player. There were rumors of Puig for Jackie Bradley awhile back so... maybe. But... I gotta believe not likely.
The Yankees have been over the luxury tax line forever so they might just keep going full speed ahead and augment the Stanton addition but... this is the first year in a long time that they have a chance to reset the penalty and I think they will try. Signing Darvish will leave them very little room to address other needs like 3B and 2B. If they acquire Cole... they will be immediately out on Darvish.
the Astros can make this deal easy but again... If they acquire Cole... They will be immediately out on Darvish. So Cole will take out one of those two.
The Cubs could make the deal happen. They are kicking every starting pitching tire it seems but something isn't adding up. The rumored 3 year 42 million dollar offer to Cobb. Signing Morrow and letting Davis walk. Letting Arrieta walk. I have nothing to base it on but it seems like the Cubs are cutting some corners in preparation for next year's FA Group.
The Rangers... They are the team that scares me. They have the need, the space and a comfort factor. I'm hoping the Darvish is just too rich for their blood.
Of course... I have nothing to base this on... besides my little head and it's ability to read between very blurry lines.
