I realize it stands for "Value over replacement players" But what exactly does it mean? I hear it used all the time here, and have NO clue what to think of it. How is it calculated, and so on and so forth. As of now, I take it as another made up stat, to make "stat heads" feel superior over non stat heads. Thats not what I mean, but, it seems like a pretty useless stat. Sorry, thats my rant for the day. I just want to know, why use it, how is it figured out, of what importance is it, and so on and so forth. Thank you, and have a nice night :)

Also since it is a counting type stat, the more playing time you receive the higher your VORP is. This evaluated a player like Larry Walker, who puts up Hall of Fame ratio numbers but just doesn't play enough to have great value. The 0 point of the system is generic AAA player who would replace a player if that player no longer could play. VORP measures how many runs added (postion players) or prevented (pitcher) by a player over that of the generic AAA player. The major idea behind VORP is average players add value to team since they are much better then generic AAA player. Most systems have average players as the 0 point of the scale.
