I don't see a single instance of anybody saying that he "Didn't Understand the Rivalry." Not in the post, not in the comments. The closest it gets is the fact that Michigan was 0-6 against MSU and OSU.
Also, the one discussion about the spread not working in this conference has one dude who makes that assertion, and 5 other guys refuting it.
The large syntax around the "being former players" is that they understand college football - not that they're "Michigan Men."
I'm guessing that we're more on the same side of the fence than maybe you think - I'm not defending Dave's post. I will defend the readers and commenters as not being as dumb as you make them out to be - you're grossly over-generalizing a few points that are either out of context, or immeditely refuted by a number of people.
