1 more legit swing/miss guy would be preferred, but that's probably universal across baseball. There's enough talent on the roster to be effective, it's just a matter of health and consistency - which is univeral across baseball.
Romano, Mayza and Yimi - while not the most imposing trio in the world by any stretch, can get the job done. Richards and Cimber are both steady and reliable. Phelps could be the huge with his talent. Merryweather has tremendous potential to be lethal. Stripling is what he is and wont be in high leverage situation.
The only real questions in the pen is whether they will get anything from anyone left handed aside from Mayza.
