I don't have a problem with bettors blowing off steam after a loss...if they can't do it here, where can they do it? It is a healthy emotional response. Stifling and holding feelings inside cause the real mental damage. If others can't handle it...tough titty.
Even though I don't buy the 'scripted' fix, others have a right to express their views. Sometimes I think this place is overrun with bookmakers. Any view put out there that this so called sport isn't legit is always shouted down.
Besides, the NFL isn't pure as the driven snow either...quite the opposite and it goes way beyond human error by the refs. The refs are complicit and can affect any outcome they choose (or is chosen for them).
