I don't really understand people who have such a beloved affiliation with something that can see through things like this. Is it the love of the school, or more specifically the perception in your mind, or is winning just that important? I'll never understand it.
I think anyone can look at this situation with intellectual honesty and understand that under the circumstances, it would be difficult for a HC to not realize that having the perfect response to everything your opponent is doing is a bit more than just being a good coordinator or assistant. Heck, you could even rule out luck at this point. The lack of a strong statement from Harbaugh is, by itself, pretty damming. You'd think that someone who was clueless about what was likely happening would be mortified that his accomplishments are tainted and tarnished by even the perception of cheating.
