"In my opinion, college football has become too commercial," inexorably repeated, has bought him to the brink of lunacy.
Be against college football for some reason or reasons of your own. If they are keen and perceptive ones, that's splendid. But even if they are trivial or foolish or indefensible, you are still ahead so long as they are not everybody else's reasons too. Be against it because the colleges don't spend enough money on it to make it worthwhile, because it is bad for the characters of the spectators, because the players are forced to attend classes, because the football stars hog all the beautiful women, because it competes with baseball and is therefore un-American and possibly Communist-inspired. There are lots of more or less unused reasons for being against college football.
Sometimes it is a good idea to sum up and dispose of the trite and conventional points before going on to your own. This has the advantage of indicating to the reader that you are going to be neither trite nor conventional. Something like this:
We are often told that college football should be abolished because it has become too commercial or because it is bad for the players. These arguments are no doubt very cogent, but they don't really go to the heart of the matter.
Then you go to the heart of the matter.
