Buzz,may be part of it.The books who put the lines up late are the cautious ones.Usually the sharps have hit the games they want by the time these places put up a line.Therefore the lines have solidified.They will use a place like this for buy back when they have more on a game then they want.The earlier you post a line the more exposure you are gonna have.Some places don't mind that exposure ie Cris and Olympic.They just want to write action.Even those places don't allow full limit bets when they first post a line.But I'm sure you know all this.LOL.
