First thing we need to know is how Junior and George – actually, probably just Junior – do on their football picks if you don't count the high school games. That is, what is their record when the high school games are factored out?
Let's assume their successful picking percentage is at least as good without the high school games as it is with them. Probably a pretty good assumption.
What we know about those picks is that over the course of a season, their winning percentage is noticeably over 50%. My recollection is that Junior usually wins, although I think that as of this week he and George are about even.
So if you just bet Junior's college and pro picks – legally, of course – at the end of the season, you will have made money.
