I understand the paranoia here but why would the head of the committee--the AD of George Mason University--be out to protect the BCS schools? It makes no sense.
I don't believe for a second that the committee put mid-majors v. mid-majors on purpose to weed them out. No way. One could argue they put majors v. majors to weed THEM out.
The committee is filled with BCS conference people and non-BCS conference people. Do you think when Doug Elgin was on the committee he was told to "look out for the BCS schools?" If so I'm sure he said screw you. Same for the GMU AD, the Horizon League commish, etc.
The individual tourney matchups are the very last thing that gets done on Selection Sunday. I would say one reason you see more mid-major v. mid-major matchups is that now, for the first time, mid-majors are actually HIGHER seeds. Before they were always the lower seed.
Now with the committee and people seeing how good the non-BCS schools are they are getting higher seeds (Drake a 5, Butler a 7)--they of course will play lower seeds who are often times non-BCS schools.
Sorry, no pro-BCS conspiracy. It doesn't make any sense and there are people on the committee every year who would NEVER go for that.
