I searched for an answer to this question on MGoBlog but didn't find anything...
It really bothered me that Ohio State was able to walk up to the line of scrimmage and call plays based on Michigan's defensive formation in the 2012 edition of The Game. Ohio changed plays numerous times even after Michigan made adjustments and/or froze our sub-optimal alignment by having Braxton Miller go under center immediately and then stand there for the entire play clock.
Is this a common tactic? I don't remember seeing a team run this as painfully effectively as Ohio did last year. This wasn't a simple huddle, walk up to the line, then audible. They literally saw the entire defensive setup, then adjusted their play at will for what seemed like the entire game. Obviously you can only do this at home, and not on the road.
Any further thoughts about how to counter this move? Ever see another team do this? Wanted to ask before the 2013 season started.
