What Sean Casey has long known about Aaron Boone shows how they can help the Yankees now

When Aaron Boone was hired to be the Yankees’ manager in December 2017, he hadn’t coached or managed at any professional level.

Having grown up around the game and having played it for a dozen years in the majors, his baseball acumen was unquestioned, but it was fair to wonder what else he brought to the job.

At the time, The Post reached out to several people close to Boone, and as it turned out, they highlighted the main attribute the Yankees saw in their new manager.

One of those people was Boone’s father, Bob, the second-generation major leaguer who also spent time as a big league manager.
