My unpopular opinion is:
MLB teams do not, I repeat, DO NOT, need a frickin "closer".
Sure, having a guy at the end of games to be an almost automatic 3 outs for the other team is nice, but isn't necessary for a team to be successful.
Nor do teams have to shell out ridiculous amounts of money for a guy who will pitch one inning once in a while.
I have seen a trend by some teams (mostly due to necessity) to go to a committee of pitchers at the end of games...basically go with the hot hand, or at the very least, if you have two or three very good arms in the pen, rotate them so the opposition doesn't get to see the same guy and get a chance to adjust.
You can get three good arms who combined make salary less than some overpaid 'superstar' closer, and get the same results...if not better.
Pitchers are supposed to be pros. Doesn't matter when they come into a game. They aren't children that "need to have a defined role". Just come in, get outs...whether in the 5th inning or the 9th.
And while I am at it....pitching in the 9th is with no one on is NOT harder than pitching in the 7th with runners on and less than two outs...……. and the clean 9th is when that superstar closer is being paid to pitch. Go figure.
Having a closer is thing of the past. Lots of pretty good arms out there that can get the job done as groups and if one goes down you have easy replacements.
STOP PAYING STUPID MONEY FOR ONE INNING GUYS... dammit!
