Just for context...
OPS+ is adjusted for park factors and position. It doesn't compare catchers to 3B. It doesn't matter if you play your home games at Minute Maid or Citi Field. Also, a 143 OPS+ means that the player has an OPS (remember, it's "adjusted") that 43% than average.
Another thing...OPS+ is a nice, easy stat. It is by no means a complete stat, and one could argue that no stat by itself should be used in isolation. Context.
Oleg is right, although you can get a little context by comparing the OPS+ to that of other players at the position.

I am pretty sure OPS+ is not adjusted for position or the median of each position would be 100.
I thought the same thing. From the article:Quote
(Aside: For this little study, any player who spends at least half his games as a center fielder had all of his plate appearances count toward this sample, so long as he accrued more than 100 plate appearances. So guys who played multiple positions, like Ryan Freel, had all of their hitting stats counted toward the position at which they played most often. Not a perfect system by any means.)
I think that may take care of the disparity.
The OPS+ number for an individual player is not affected by the positon he plays. That article is attempting to explain how positional averages are calculated and is really meant for the hard-core SABR geeks. I doubt if most fans care whther Ryan Freel's numbers get lumped in with centerfielders or thirdbasemen.
