When you are the most powerful conference, you tend to flex your muscle. The ACC is doing that on the basketball front. The league is making a proposal to expand the NCAA Tournament field to 72. They also want some general rule changes like, pushing back the 3-point line, shortening the shot clock and expanding the lane.
Because the ACC tends to be one of the deepest leagues, the expanded tournament makes sense. It means one more team makes it. Because a few more game also means a few more dollars for the NCAA, I imagine this one will pass.
