Obsessed With OPS+?

You might be asking yourself, what is OPS+? Don't worry, it's not that complicated; OPS+ measures the performance of a player against the rest of the AL or NL in a given year.

An OPS+ of 100 is considered league average performance. Anything above 100 is above league average. Conversely, anything below 100 is below league average. Fairly simple.

However, what's considered league average fluctuates from year to year. It fluctuates even more dramatically from era to era. That's why you may be surprised by where some of the names fall on this list. I know I was. One thing to remember is OPS+ is adjusted to a player's ballpark(s).
