Well I guess that depends what they script. I will concede that Falter finished the season as our 4th starter, and thus far has been saved for that role. But given the top of the Braves' order I would still consider an opener - yes, even Gibson if Thor were somehow to be needed tomorrow - and barring that I think they'll be planning on a tandem. A plan Falter could cancel by getting 18 guys out in five or six innings, of course! Ranger's start wasn't a "bullpen game" or tandem but he still only went 3 1/3.
The easy answer to this is to get 7 strong from Nola and then just about anybody is available before or after Falter, without Gibson or Nelson ever coming up.
