They actually don't have a ton of depth (which is evident by the fact they are starting Grant Holmes in a MUST WIN game). They got 177 innings from Chris Sale, 134 innings from a 1st year converted RP in Lopez, 113 innings from a guy who started the year in A+ ball and 165 innings from a 56 year old Charlie Morton. Elder, Winans, Vines, Waldrep, etc. were all pretty useless to them. You don't have to squint very hard to see the Braves rotation was pretty lucky this season to be where they are. I mean - it worked, but the probability of this happening were probably <5%. Even you should be able to see that.
