Bill Belichick thinks it's legal to video other team's defensive signals and practices and has been doing it since becoming New England Patriots coach in 2000? I guess he thought cheating on tests was OK in school also. Aren't sports competitions of any sort like a test...a test of each others skills and preparation?

Roger Goodell, NFL Commissioner said he confronted Bill Belichick in September, or maybe before, about the illegal taping from the sidelines and Belichick interpreted the league rules in a different way than he did.  They agreed to disagree.  That's not good enough! The $500,000 fine is not good enough! Suppose every coach taped each other defensive signals or whatever they chose to be of interest and advantage for their team.  Where would this lead the competition between teams?  I think it leads to the whole NFL system falling apart. Part of the preparation is to try to outfox the other football team, not already know what they are going to do!
