I've brought this up in the past but what about a 4 man rotation that has a piggyback. Basically 8 starters that combine to go 7-8 innings limiting pitchers to 60-75 pitches.
1)Peralta-Hall
2)Rea-Ashby
3)Civale-Woody
4)Myers-Wlison/free agent vet/trade acquisition/Hudson
Bullpen- Megill, Hudson, Koenig, 2 of Mears, Yoho, Paredes, Bauk, Wilson Payamps, Hoby, Uribe, Peguero, vet/trade acquisitions (assuming a Devin trade)
Misi, Henderson, CarRod, eventually maybe Gasser, Wichrowski, Smith, Hunt, provide depth. If injuries hit it gets easy to pivot to a 5-6 man rotation. Each guy in theory goes 3-5 innings 40 times a year, rarely would a guy go through a lineup a 3rd time. It also allows some of the injured/young guys a way to build up innings. A 5 man bullpen would not get overworked especially if we have a couple solid taxi guys. I would assume the piggyback would usually go 7 innings, rarely 6, sometime 8, once in a while 9.
I get that our pen depth is a strength and this doesn't really help. In reality we should probably try and turn some quantity in a high end starter. Just a fun idea to think about.
