I am not sure if this is original or not but I thought I would try an idea I had. The idea is to find games with large spreads (example, Houston -34.5 vs Tulane) and bet the favorite and the under. It just seems that for the over (73.5) to hit, the spread will most likely be covered by the heavy favorite. Likewise for the the underdog to cover, the under is most likely. The key is to get some unders that also cover.
It just seems like there is a higher chance of the fav covering with the under than a powerhouse letting a scrub team run with them to the over and underdog cover. What do you guys think? Will be trying it out this week with ~21 point favs.
