We talk about the Luxury Tax and its impact on spending as if we know what we're talking about -but in some ways we don't. We don't because we don't know how much teams are willing to spend on salaries + luxury tax, with the luxury tax being considered a cost of doing business.
We do know that they Yankees are already in the 50% bracket for luxury tax, having spent beyond the limit for four or more years, but does it matter to them? According to this link http://www.cbssports.com/mlb/eye-on-baseball/23592770/report-yankees-set-to-pay-record-291-million-luxury-tax-bill (which may or may not be accurate as every place I look has different numbers!) the Yankees had a payroll of $236.2M in 2013 plus a luxury tax hit of $29.1M bringing their total cost of putting players on the field to $265.3M.
The purpose of this post isn't to whine about the difference between that $265M the Yankees spent and the <$178M the Red Sox spent. Rather it's to ask why we think the Yankees aren't going to spend this kind of money again. They obviously have it! I see no reason to believe that they're not going to exceed the $184M cap in 2014.
My point? We're wasting our time speculating on what the Yankees will do and thinking that the Luxury Tax has any bearing on it. Don't believe their BS about wanting to come in under the $184M cap. The Yankees FO has a history of playing fast and loose with the truth. If Cashman told me that water is wet I'd seek a second opinion. They're not done and the luxury tax cap doesn't mean much to them other than it being another business expense.
