The last minute trade

Sure, they’re a good team, but they can get better.
So, at the trade deadline, they shopped their star outfielder for a third baseman.
And the rest of their infield for starting pitching.
Their starting pitchers were dealt for a new outfield.
While the rest of their outfielders were exchanged for some bullpen pitchers, a closer, and a better catcher.
Another catcher came in an even deal for their existing catcher.
The next day, the locker room had a whole new bunch of guys suiting up.
In uniforms that the equipment manager had just barely finished sewing on their names.
