I can sort of see why you are doing this. You'd think that players/ex-players etc would be able to judge a game pretty well. That's not really the case though. You don't have to know much about a sport to beat it. Just have to be decent with statistics and creative.

"Money talks.If no-one wants to buy,bookie needs to make the price more attractive by lengthening the odds"

Remember most bettors don't care about the odds. If they did, the TABs would be out of business.

"Have your people ever played a game of football in their lives?."

What do you mean by 'my people'? The only picks I've posted here are Super 12 picks, and yes I played rep footy.

"These tipsters lives revolve around football."

If you are using statistics and a computer model you don't need a knowledge of the sport at all. If you are basing picks off your own opinion then yes you do need knowledge of the sport.

Seeing the prices does not necessarily make biased opinions. Course it's always better if you have formed an opinion first.

I'd be surprised if most sportsmen could beat the bookies at their own sport. I'd say the % who could is a small minority.
