The New York Yankees never fully rebuild, but we have seen windows open and shut. Re-tooling is probably the better term — turning over the roster and infusing it with young players. The last time the window needed to be reset, we saw the Yankees sell at the 2016 deadline. Most of those moves didn't actually pay real dividends, but they set the stage for Aaron Judge's ascension and the opening of the current window the club is navigating.
With the meat of the roster aging, we're likely going to see something similar happen again soon.
