No matter how good you are and how many winners you can pick in a row it really does not matter unless you have proper money management. When it comes to sports betting this is all that matters. Leonard Tose could win 99 games and through a hail mary on the 100th and lose it all as he did on the Philadelphia Eagles.
So my think tank advice is device a system if the 2% doesnt work for you than try something different. It's all about paying your tuition in sports and that tuition bill may be hundreds of thousands of dollars but once you find a system that works for you, fits your personality, and can be managed properly than you have a good thing going.
