With your plan, I think you beat up the bullpen even more. You say the piggyback starters would average 8 innings? That wouldn't happen. If the game is close you would still use 2-3 more relievers. A LOOGY maybe, set-up man, closer. Plus, what happens when starter#1 or #2 can't get through an inning or two? That's going to happen. Just no way those piggybacks would average 8. So basically what you're doing is cutting the bullpen from 8 to 6 arms, and they will be more over-worked. Plus, it still doesn't make sense to me why you would take a Suter or Miley out if they're cruising through 4 with a 6-1 lead. Yes, yes, they're not as effective 3rd time through the line-up. But with a 6-1 lead, 4-0 lead, etc. there's room for error. Sorry, just makes no sense to me to pull out a starter who could easily eat up 2-3 more innings just because it's time for the piggyback guy to come in. Lots of other reasons I don't like this idea, that's just some of them. Why make it so rigid? Maybe those piggyback starters are needed in other games started by Anderson, Chacin, Davies. I think the key is having at least2-3 guys who can pitch multiple innings, and we'll have that. Numbers say you don't beat up the pen more. If the game is close you want to use 2-3 relief pitchers. 2 max 8th and 9th. But likely no i dont. That's old thinking. What if your starter can't go through an inning or 2? You lose. The other guy comes in an tries to eat 6. Why take suter miley out after 4 innings cruising? Where do they come up in the order? How many outs? Anyone on? Have they faced the lineup twice? I trust the next guy to pick up the lead and run with it. Its his job. You could squeeze a 5th if the right situation presents itself. That makes for a day where 2 guys go 9 ip. Up 4-0 faced 15, not due up. Ok go 5 and let the other guy finish it because he shouldnt allow 4 in 4ip. You can say he could eat 2-3 more ip and he could also decline and flame out and blow the lead. I'm playing numbers... your pointing to hypotheticals that would lead to a loss no matter how you pitch it. Why so rigid? To save the pen. What if one of the top 3 implode... well if its anderson, guerra suter are on their throw day. If its davies, woodruff miley are on their throw day. They can each go 30-40 pitches. If its chacin... load up barnes jeffress and logans throwing a full ip. You will likely lose anyway so who cares. Just get the game over with in the least taxing manor possible. They can average 8... they can also cover 1 of the 3 starters if all goes wrong. They can cover their piggyback guy if he implodes. If the 2nd guy in the piggyback implodes, well, that sucks. Time for the pen.
