Every year, I tell myself; to be very carefull when baseball season is over. In that I usually make a very small profit. But, of course, every year, I must bet football and Basketball. I can not remember when I EVER had a winning season.
I have no idea what the percentage of winning players longrun is on this board or in general population. My guess is that it's pretty low say about 10% or so. The books would not keep opening year after year if there was not a decent profit in it from their end. Don't be fooled by all the so called experts. For the real expert will NOT blow his own horn.
