As we have proven, the so-called NBA zigzag theory is a virtual wash. It is above .500 long-term but a slight loss with the juice. However, various bounce back angles, which take several other factors into consideration, do win long-term. There are quite a few here, but most follow the theme of the better the team and the bigger the previous loss, the more likely they are to bounce back. One says a big favorite off a big loss is 81-38.
