You can see the parallels, can’t you? A year ago, the Yankees held Brian McCann as a veteran pushed out of his old job, armed with a full no-trade clause. Now, the Yankees hold Jacoby Ellsbury as a veteran pushed out of his old job, armed with a full no-trade clause. For the moment, those parallels stop there. Which is why Ellsbury following McCann’s trail out of The Bronx this winter doesn’t rank as a slam dunk. Such a transaction will require far more effort and financial sacrifice on the Yankees’ part and, likely, more open-mindedness on Ellsbury’s part. Consider this for starters: By the general managers’ meetings last year — which actually took place a week earlier on the calendar — Brian Cashman already had engaged McCann and his agent about the situation. As of Tuesday afternoon, Cashman had taken no similar action with Ellsbury and his agent Scott Boras, a reflection that an Ellsbury trade doesn’t rank among the Yankees’ top priorities. “We haven’t had any discussions other than status quo, as far as I’m concerned,” Boras told The Post at the GM meetings. “I haven’t even approached Scott,” Cashman said. “They have the full no-trade for a reason and I would walk through that process with the highest level of communication and respect because of it. And so I haven’t connected with Scott at all, but I know he’s here somewhere. I know I’ll get a chance to talk to him before I leave, just generally about everything Scott Boras-related for the winter, and I’m sure we’ll also talk about Jacoby as well.” Ellsbury experienced an up-and-down 2017 with the Yankees, missing more than a month recovering from a concussion and registering a .264/.348/.402 slash line in his fourth year of the seven-year, $153 million contract that has proven to be a considerable overpay. While he put up his best month (.337/.436/.477) in September, helping the Yankees secure the top American League wild-card slot, he then vanished in the postseason, starting just four games (all at designated hitter) and finishing 0-for-9 with two walks.
