Larry, I'm not saying that it's the main reason, but instead just looking at things from the opposite point of view of the original poster. Sure it sounds like it's no biggie that "Miami merely asks a kid to be average in the classroom" but when the kid can get into other bigtime programs that have a lot to offer, that's a problem. Also, the fact that you brush off a kid or two per year as if it's nothing is alarming. I'm thinking that's the same line of thinking that the university has. A kid or two per year can make a huge difference.
At any rate, I don't want this to get into a back and forth about grades because that wasn't my main point. I just think it's a bit disingenuous to ignore the role that UM may have played in this.
Edit: One last thing. According to some on this board, the Tracy Howard's of the world appear to be up for bid.
