Taking Headley back to help them with their payroll crunch is about as counterproductive as it gets.
Make sure I get this right - you want Andujar so bad that you're willing to swap Garcia for Headley (more or less salary neutral for this season), AND tie up $13 million (instead of whatever Adams stands to make in arbitration next winter) of our 2018 payroll for someone who will contribute less offensively if he plays every day than Adams would off the bench?
The Yankees HAVE the money - they just don't want to spend it. That's their problem. If I'm giving them two pieces they can really use because their fans are pressuring them to win this year, let Cashman do his job and figure out if it's worth going to ownership to find out if it's OK if he exceeds the cap to do so. If they absolutely have to have some salary relief, tell them we'll take Aaron Hicks' and Adam Warren's money back - they're not guaranteed anything next year - that would help with their roster crunch plus cover Adams' money AND clear up their OF logjam.
I like him and all, but Andujar isn't a good enough prospect to be trading useful MLB pieces AND taking on useless dead money for - and Headley would do nothing but get in the way here. If Andujar needs more time, we've already got Rodriguez.
Are you sure you're not a Yankees fan?
