I believe our bullpen got into trouble partly because Odorizzi and other starters, while not having bad starts, were only lasting 5 innings, maybe getting pulled in the 6th. A whole pitching staff can't rely on having good starts max out at 6 innings and expect 3-4 guys to remain fresh and effective for long stretches. Which, yes, I think maybe that's where this "6 man rotation" idea comes from, but I still don't think its a good idea. If Odorizzi is your ace and he gives you a solid 5 and a third, then Berrios goes 6, that puts a lot of strain on the bottom 3 guys as well as bullpen.
