re: Can somebody intelligently explain what the pre-snap motion is supposed to accomplish

Some, like yourself, blame Miles for this shite show. I am sorry, but O was a major contributor to recruiting during Miles final two years. Most of the OL and DL transfers have occurred under the great O. So where did he do a "damn fine job"? They seemed to do ok after taking over last year with what Miles left them, but this is O's product now and, whether you want to believe it or continue to blow O, it's pretty much what most fans expected. Miles definitely contributed, but this is O's team. It's O's team crapping in the bed in 2017. So, bull shite all you want.
