I just see a lot of teams seem to get so many more innings out of their high priced relievers.
True, but usually, they are not involved in as many saving situations than teams that keep their closers at 80 innings.
In the following team, for example, I had F. Rodriguez to throw 181 innings. Stadium was Cadmen Yards, so not the best stadium for Rodriguez, and it showed (35 homeruns allowed), but when I turned to free agency, there were no more top closer left (it was a 24-team league).
http://365.strat-o-matic.com/team/1423010Here was the settings for F.Rodriguez. Team strategy for closer was set at regular, not maximize, as suggested by rolandzeut. Also, I had pretty much the same settings except for two differences: Rodriguez was not set to pitch "behind & late" (I prefer to use my #3 reliever for that role) and more importantly, I had him as my second middle man (for most of the season).
The upside was 181 innings.
The downside is that F.Rodriguez was available for only 23 of all 79 closer situations. Let me just say that my team has been very lucky that my other relievers stood up so well was Rodriguez was getting tired.
From my experience, for a starting rotation with short stamina, I would say that the following roughly stands (for a R1/C6):
Middle/setup/closer: 180 innings; finishes roughly 30% of all closing situations
Setup/closer (7th or later): 130 innings; finishes roughly with 60% of all closer situations
setup/closer (8th or later): 80 innings; finishes with 90% of all closing situations
"Maximize" only closer: 50 innings; is involved in all closing situations (except blown ups)
