Hill can't continue to pitch like this, and if going to Iowa for a couple turns is what's necessary for him to get right, then that needs to happen. However, ignoring the organization's treatment of him as a possible cause for this Ankieldom would be foolish. They tried changing what works, a dumb dumb dumb thing considering Hill used to be Rick Vaughn before they straightened him out, sees a sport psychologist(aka if you don't need to fix him, then don't poke the bear), and there's no benefit to be gained from the tinkering(Hill already had a deceptive delivery, great peripherals, and has zero injury history).
