I don't think anyone with a pulse would dispute that the BCS is broken. Reading your posts, I just get the impression you're viewing one particular issue through green-and-white glasses.
Neither the human voters nor computer rankings care that
Team X played an "extra game", or made it
to their conference's championship game.
Team X gets rewarded for winning that game, or, penalized for losing that game. With or without the BCS, that's how these things work in any sport I can think of.
As for number of home versus away games:
U-M: 8 home, 4 away
MSU: 7 home, 5 away
UW: 7 home, 4 away, 1 neutral site
I don't think U-M's
one extra home game somehow poisons them or otherwise puts them in a different class. Given the option, most schools will choose the same home-heavy schedule. That's what pays the bills these days.
As for strength of schedule, all the computer rankings I can find disagree with your assessment. Not that it matters much, you just haven't described how you've gotten that notion.
Sagarin:
U-M: 38
MSU: 55
UW: 64
Anderson & Hester:
U-M: 25
MSU: 59
UW:64
Colley Matrix:
U-M: 30
MSU: 73
UW: 77
Massey:
U-M: 37
MSU: 38
UW: 50
Again, even if you reject the BCS system in its entirety, or the computer rankings that it uses, there's really no room for CCG losers to obtain at-large invitations unless there are particularly weird circumstances (like those I described earlier). Lastly, a 10-3 record isn't attractive enough to the bowl committees to merit an at-large invitation. It's just not borne out historically. And, as much as I'd love to see it, having a 16-team playoff wouldn't guarantee solutions for these lesser issues any better than what's in place now.
The Big Ten Champ goes on to the Rose Bowl. The Big Ten CCG loser finishes 10-3 and still gets a decent non-BCS bowl date. If, somehow, the right combination of teams winning and losing sets Michigan up for an at-large bid, so be it. Everybody splits their revenue with the conference. I just don't see the big deal. Is there anything more to your argument than hating on the Wolverines?
