At what point can they just plan on using a Mejia/Gee tandem? If these two can both go through 4 innings effectively, just do it. If Gee knows it's coming, he can plan for it like a normal starter would rather than think of himself as a reliever who may or may not get the call on any given day. If they can turn two marginal starters and one reliever into the same results as one very good starter and 2-3 relievers... I won't say I prefer the marginal starters option, but I will say it's what we've got access to. Might as well do it on purpose.
