"The latent causes of faction are thus sown in the nature of man, and we see them everywhere brought into different degrees of activity", James Madison, Federalist #10.
When Madison wrote about the dangers of faction, he was concerned that competing interests would destroy the nascent American government. If we turn to Michigan football and its current coach, one might think that there are only two factions: the pro-Rodriguez and the anti-Rodriguez. But these are not monolithic factions. Members of the anti-Rodriguez group have all sorts of motivations: some overlapping, some singular. Some are personal, directed at Rodriguez. Some have nothing to do with Rodriguez himself and everything to do with his job.
It’s important to know who you’re dealing with. So when you encounter a card-carrying anti-Rodriguez person in the wild, please refer to the guide below. Your combatant may have one, some, or many of these motivations. Disarming them is nearly impossible; it’s best to walk away. The Just Win, Baby
This is the most legitimate type of Rodriguez basher. They point to his 8-16 record, his 3-13 Big 10 record, the end of the bowl streak, the end of the winning season streak, etc. They just want the team to keep winning like it always has and can’t understand why it’s losing now. For this group, any losing record is unforgiveable, and two in a row is a death sentence. Almost every Michigan fan is a member of this group to some degree; the difference is between those who see progress out of a deep hole vs. those who think a good thing was driven into the ditch. The Devout Nostalgic
Somewhat similar to The Just Win, Baby but less pragmatic and more unrealistic in expectations. Believes Michigan has a divine right to have a winning program, and anyone to divert Michigan from that divine right must be Satan himself. The Traditionalist
Maybe more realistic than the Devout Nostalgic, yet still upset about any change to the football program. This includes the spread offense, piped in music, the handling of the #1 jersey, the lack of season-starting permanent team captains, etc. For this type, Rodriguez is not a ‘Michigan Man’ and never will be. The Distrustful
This group has problems with Rodriguez because he can seem like a glib gladhander. They are put off by the way he left his alma mater, the lawsuit (whether it was encouraged by U-M or not), the golly-gee press conferences, the failed real estate deal, the GPA claim, the Lion King quotes, etc. They don’t fully trust Rodriguez and likely never will. They also know that this feeling is somewhat irrational. [Full disclosure: I'm an occasional member of this group] The Football Hater
This person hates football. They hate big-time sports. They may have tolerated Lloyd Carr because of his emphasis on character and academics and charitable work, but now that Carr’s gone this group is out in full force. The Puritan
Rodriguez swears. Therefore, he’s a bad coach. Anything that any member of the program does is wrong and further proof of Rodriguez’s evil core - regardless of similar things happening under previous Michigan football coaches or at other programs. For this person, a minor NCAA violation would be the equivalent of a double homicide. The Media Elite
Perhaps after years of getting dressed down by Lloyd Carr, the media elite is exacting his revenge on the Michigan program. While Carr intimidated the press, Rodriguez does not. And rather than repay his humanity, they take advantage of it. 'I Wanted a Different Coach'
These are legion. For whatever reason, they wanted another coach (Miles, Ferentz, Kelly, Harbaugh, English, Hoke), and since Rodriguez is not that coach, they want him out. The Vengeful West Virginia Hillbilly
DO NOT UNDERESTIMATE! West Virginia is a beautiful state and West Virginians can be beautiful people. BUT THEY DO NOT GIVE A SHIT. They have elected a crotchety former KKK member to the Senate for 50 years. West Virginia is also the state that gave us the Hatfields and McCoys; long-running feuds are nothing new to these folks. They feel betrayed by native son Rodriguez, and they want nothing less than the nuclear annihilation of Rodriguez and anything associated with him – including the Michigan football program. They would think nothing of sowing discontent wherever possible. So, every word you read, every voice you hear, everything you see, you must ask yourself - is a pissed off West Virginian behind it all? Maybe yes, maybe no.
I hope this helps. Remember, Madison said that the causes of faction cannot be controlled, only the effects. So do your best, and please feel free to add to the taxonomy in the comments.
