I'll take any empirical evidence you have, but you can keep your intuition. Throwing 100 pitches 5-6 times a month compared to someone throwing 20ish pitches per outing (not counting the games they dial it up, sit back down, dial it up again, etc.) and throwing 15+ times per month, gives them less rest between outings.
For the people who said he'd only throw maybe 110 innings next year: We just watched Sanchez go from 92.1 innings to 192 in one season. Would Osuna go from 74 to 174? Not likely. But it still means he could throw 120 in the pen, and use him for 20-30 more innings. And lol at going from 110 innings one season to 140. More like 120-180 at least.
