Well take baseball with the 1.5 runs line. I believe something like 21% of the games landed on 1 run. So if you were to bet every game on both teams in each game +1.5 runs you could make money if you had the right money management. I would think you could so the same for just about any sports (PRO).
I like middles but only in football. I do like the idea of using say NBA games. IT does seem that many games land within 2 points of the spread (which would be 4 points if you bought 2 points each way.
