Yea.
See, I like 10/15s dur, 60-90 sta more than the next guy, but as spot starters. Start, rest until the next start 7-9 days later. 18-21 starts, 120ish innings
If they do relief and have to come in on back to back days, I find yer screwed. And yer screwed because with multiple ones, they're forced into that scenario.
