This is not about the Dolphins, but rather the Hurricanes:
Some years ago, the Hurricanes joined the Big East, in the hopes that their basketball team would improve because of the competition. In return, the other school's football teams would get better. Never happened. Miami's hoops team was not allowed to compete in the Big East, so they never improved. But, the football teams all get better because of the competition, and Miami's got weaker to a degree.
Then, Miami joined the ACC, and the basketball team did get better. Better than the football team. The hoops squad is 7-0 at the moment. The football team finished a disappointing 5-7.
