I wouldn't be opposed to them using a committee throughout the playoffs, especially if Severino comes back. Tanaka, Happ, Paxton, German all can't get out of the first inning without giving up runs.
Maybe start Green and Severino and let Tanaka, Paxton, German do the middle innings. Then the rest of the pen to finish it. At this point they going to have to get creative, because current staff isn't good enough. We just got swept by Fiers, Bailey, and Roark - They're not Verlander, Cole, and Greinke/Miley
