I think that article hit the nail on the head and I will add to that the fact that these teams consist of college STUDENTS and IMHO, they've got enough on their plates trying to maintain satisfactory progress in their classes
AND cope with the demands of a 12 + game season. I definitely think the BCS could and should be improved by adding the old strength of schedule component back in. For the most part teams that play a hard schedule are treated the same as a team that schedules cupcakes which doesn't seem correct.
Cheers!
