No name teams

Why does NCAA put no name teams into the bracket. They have no chance at winning where other teams do. Yes, they put all the conference champs in but I think they should put the best records in first. Michigan, Florida, and San Diego State should already be in the brackets but yet they are still on the bubble to get in. They should take out Binghampton, Morgan St, Robert Morris, Jacksonville, CS Northridge, and Stephan F. Austin. Why should Michigan and Florida suffer not being in the bracket because these no name teams were picked to be in the bracket.
