> “It got a little out of hand this season where it became more of a line-calling game and a sweeping game as opposed to a throwing game,” explained Miskew. “We don’t want it to be about the fabric on your broom head. We want it to be about throwing it [the rock] well.”

So it sounds like they make the throwing part of the game "obsolete" since the sweepers have so much control that it doesn't matter how bad the throw was. So it's unbalancing the game in unexpected ways.
