What's worse is that it's rarely even discussed as an option. Has there ever been a report about backups all trying to get in edgewise by demonstrating knuckleball aptitude?
It's basically assumed to be Thole every year, except for the Martin-Navarro logjam last year. And even then, there was a huge portion of time when the team carried all friggin' three, which says volumes.
This doesn't really seem to me like a mid-season change. It should have been considered when building depth, and even Shatkins glossed over it.
