The Sox bullpen was terrible last year. Check this out LINK. I hate using one fact to counter your point, but the Sox bullpen allowed the most inherited runners to score than any other team last year with 127. Dead last. Next closest team were ironically the Cubs at 91. Even so, that's still huge separation. Both Colome and Herrera aren't "sexy" arms and may not move the needle as much as the Sox need it too, they are far better than any other option at the moment and help solidify the backend of the pen for a young group of starters. It's a step in the right direction and allows guys like Hamilton, Burr, Burdi, Vieira, and Frare to be used properly as they get acclimated and develop at the MLB level.
