Erasmo, Moore, Gonzales, Povse, Miranda, Felix even... plenty of options for #4/5 impact. Need a top 2 starter for sure, pushing Leake to 3rd in the rotation.
I can't be understanding the "1 arm, either rotation or bullpen" quite right. Anyone seriously thinks 1 arm right now is going to make the difference? I think 3 is more like it.
