Every year since 2010, I have used a formula of my own devising to project the scores of every college football bowl game. It has proven to be fairly accurate, going 62.8% correct straight up and 55.1% correct against the spread in the seven combined years. It’s my understanding that 55% right is the threshold for making money off of picking games — I don’t do it and wouldn’t recommend it to anyone else — but I’ve bested 55% ATS in five of eight years.
Here is a link to my 2015 post about the projections with links to the first five years if you want to look at the track record by year.
