There's been a lot written and said about the Boston Red Sox's need for a frontline starting pitcher this winter.
A rotation of Garrett Crochet, Brayan Bello, and a host of unknowns can probably get the job done on paper, but it'd certainly help the cause for the front office to bring in a legitimate co-ace to support Crochet's lonesome heroics atop the rotation.
However, those "unknowns" aren't merely replacement-level options. Sure, Kutter Crawford may never be more than an innings-eater when healthy, and Patrick Sandoval, Hunter Dobbins, Tanner Houck and Ricard Fitts are all trying to climb out of the injury abyss.
