meaning there is no "right" answer. For sure many managers see the benefit in using several pitchers in a game. The basis of that lies in the data driven analysis and keeping throwers fresh so they can pitch more often. More often but only an inning or two.
I think it started a few years back when the Padres began using it during spring training.
I once thought of something like that a number of years ago. You get 4-5 quality "starters" (not relievers) and they all pitch every single day-but only for an inning or two. Instead of pitching once every 5-6 days they pitch every day along with all the starters.
Old schoolers will point to the one or two times that a starter was pitching well enough to go "the distance" when he is pulled to bring in a reliever and it blows up. They will say "see that's what's wrong with data driven baseball". In truth those are merely exceptions and clearly the data has proven this method works because so many clubs use tons of pitchers-which slows the game. I do think a new rule was designed to address this-I just don't know what it is.
