I mean I'd counter that with saying I agree - we've got a ridiculously deep pen. Elder is struggling, presumably on his way to blowing past his career high in innings, had thrown 85 pitches and gets brought out to "gut through" pitches 85-97 over this old school "have to get 5 innings out of him mentality" - if anything, prepping for the long haul and knowing Elder at this point is likely going to be counted on in the post-season, now is the time to avoid over-working him just so we can say he "gutted out 5 innings"
So I would say I agree with you - lets not let traditionally customs stand in the way of keeping the team fresh for the playoffs. Now is the time to be keeping our starters fresh and not over-working them - and certainly not over-working them when they are pitching like ****.
Its the same thing with Strider. He's an ace and the future - why have this mentality of need to save the pen at the expense of the most important arm in our organization? Yet Snit will frequently bring him out for the 7th, stretch the pitch count and then only take him out after he struggles.
