Now solve for x. Seriously though, piggybacking off the Murray Chass thread, I think some of these stats could be introduced without too many problems. As someone (I think it was Derwood) mentioned, there are probably a lot of baseball fans that can't calculate a basic stat like ERA. However, I bet a lot of those people have a relatively good idea of what is a good ERA and what isn't, even though they can't calculate it. Same goes for OBP, SLG, etc. As I mentioned in another thread, the big thing is introducing them with the proper context. You can explain a stat and what it measures without the listing off the exact formula. You can provide leaderboards, showing how players rate against other players. Honestly, I hate to say this, but this is where Baseball Tonight could actually have some value. Have a five-minute segment each Sunday before the Game of the Week where someone (ideally someone other than John Kruk or Dusty Baker) explains the use of one of these more advanced stats. Explain what it measures, explain the value it brings as opposed to a related traditional stat, and show a few examples of players that rate high, low, and in the middle of the pack using that statistic. Even if no one is educated by this, there would be entertainment value listening to Joe Morgan complain about it during the game broadcast.
