Our disconnect here is that you are treating the Jenkins conversation as "he should have been here a couple weeks ago" and I'm treating the Jenkins callup as an ever-changing discussion.
It didn't make any sense to call up Jenkins when Culpepper was called up because over the next 4 games we faced 3 lefty SP and The Miz. That's a PERFECT time to call up Culpepper, but basically the worst possible time to call up Jenkins. So they didn't.
If Jenkins had already been in the majors for a few weeks and we hit that yes stretch, then yes, I'd want him playing probably 3 of those 4 games, but in the moment last Thursday, it didn't make any sense to call him up.
How about now? Yeah. Call up him. Absolutely. He's just as ready as he was before. He seems Healthy. And 3 of the next 4 SP we face are righties.
