If Romano and Swanson remain what they've shown they can be, and if Green can return and be the Green we've seen....AND if Pearson stays healthy and is able to become what we've all hoped he could become, then that's a wonderful 4 to start with. I've been as hard on the pen as anyone, but I would be really surprised if they couldn't cobble together another 4 to add to that that are effective and can get the job done more times than not.
I'd love to see a lights out lefty added, but that's a deadline cherry on the sundae kind of piece.
