hmm - only question for linus its proven if you can win 60% for a 5 year period you can turn 1k into 550 Billion - so either your a Billionaire or you arent winning 63% on a large volume of games
that being said - the problem with systems is they are either too broad in scope they NEVER win all the time - or they are too specific in scope no one wants to put their whole bankroll on 5 picks a year......
Systems are a dime a dozen - you can follow them - invent them - or ignore them -
mort olshan of gold sheet always said never bet on a bad team or never ask a bad team to cover the spread -
now its true the higher a teams Winning Percentage is the more likely they have a Winning record Against the spread - Teams with losing records often have a better shot of having a losing record against the spread. Unfortunately its not as simple as bet on the team you think will win the game - if it were that easy everybody could easily beat the game
someone online during college basketball had a winning strategy betting against home favorites if they were ranked 180 or WORSE - and were favored by 5 or more points I think
it does make sense as bad teams have a hard time winning - how can they win and cover - the problem with the spread is college hoops has tons of games - it creates a LARGE volume of plays and it had some great weeks and some not so great weeks
as for football - in college - its best to stick with talent as it wins and covers more often then not -
in pro football - bet against home favorites that have a losing record -
it wont make you RICH during a season - but it should keep you on the plus side of things
Good Luck :)
