Really. Thinking only about the merits of Rob Chudzinski and Mike Pettine when each was hired as the new coach, which generated more confidence that he would succeed? Another way to think of it: if you had Chudzinski 2013 vs Pettine 2014, who would you rather have?
Don't factor anything about the front office or the owner into the comparison. Or if you do, consider each guy dealing with the current front office (not the perception back in 2013).
Man to man. Mano a mano. Face to face. Chudzinski or Pettine, Day 1.
