Craig Breslow.
Going into his tenure as POBO for the Sox, he had Devers, Sale, Story, Whitlock, Pivetta, Martin, Yoshida, Casas, Duran, Abreu, Houck, Crawford, and Bello.
He also had the third ranked farm system ITL with names such as Mayer, Anthony, Rafaela, Teel, Campbell, Yorke, Fitts and more.
He had so much talent to build around, instead, most of these guys are gone, or not optimized because of his horrible roster construction or bad coaching hires.
It was simple, you develop the guys that you had, and build around those guys with outside talent who can produce. Instead, Breslow has done the opposite, put together awful rosters, and alienated players, execs, and coaches.
Unfortunately firing would lead to no one wanting to take the job, as they would fear they would only have it for a few years, but at this point you have to.
Eddie Romero has played second fiddle since Dave Dombrowski and I believe it is his time to shine. Let him build this team from the ground up, he deserves it and I think he would do an amazing job.
Breslow sucks, simple as that. Hopefully his employers realize that soon
