On paper it's one of the better rotations in the AL. Getting from paper to the mound is the trick. No worries in choosing an ace, a more useful conversation would be in juggling the rotation so opponents get a different look from game to game. Taj, Abel, Zebby and Pablo are power pitchers; Ober and Kremer, finesse pitchers relying on control, Prielipp and Ryan have unique approaches emphasizing release points and out pitches. That's eight possible arms, you can guess the number of games lost due to injury. Hopefully four of em make it through the entire year unscathed and not in need of a reset.
