I've seen several people mention it in a couple of different worlds. I don't think any of my teams have been hit particularly hard w/ injuries, but have seen some team really take it on the chin. However, as best as I can tell, no one really has an idea what a "typical" season of injuries is. Perhaps this can establish a current baseline over many worlds, at different points and give us something to at least compare to next time we think "are injuries up/down?"
anyhoo, my worlds:
plumpyrules!!!!1111 ML - 20, MiL - 91, we're in the 1st day of the playoffs
Fingers ML - 14, MiL - 92, we start the league championship series tomorrow
Ripken, Jr ML - 8, MiL - 14, we're 4 games into the season, so some of these are carry overs from last season.
