This is a great framework. Like TT I think there's value in delineating between the short relievers who are in the "circle of trust" vs. those you feel good about but maybe don't trust implicitly, but that's the biggest nit I'd pick.
I think framing it like this also shows you what the team needs and what we'd want Jed to buy at the deadline if it were coming up. The team's SP have not been great, but the team do not need just a SP. They've got plenty of guys you trust for 15-18 batters. Jed should add someone who you're not horrified to let face a batter for a 3rd time, or not even bother. On the RP side it's similar, you'd want someone at minimum in the Almonte zone, ideally an immediate circle of trust type. There's not a lot of value in a lottery ticket or a warm body who can eat some low leverage innings. We have those already.
