Can anybody tell me why the BCS is the most flawed system in football?

Let's examine two teams. Michigan and USC. Same record yet Michigan plays in a weak conference. USC is somehow ranked 19th while Michigan is 12th. Both of these teams have a huge upset on their record this year. They both played Oregon and Oregon beat the wolverines 39-7 while USC lost 24-17 (at autzen stadium.) Screw all of the pollsters who are biased against West Coast teams!
