Isaac Newton clearly had the college basketball bubble in mind when he postulated that for every action there must be an equal and opposite reaction. As one team's stock rises, another's must inevitably fall.
In the past week, 10 of these teams have significantly improved their odds of making it to the NCAA Tournament, while the journey has become just that much more difficult for the other 10.
Keep in mind: just because a team's stock is up doesn't mean they are in the tournament field; likewise, a falling stock doesn't necessarily mean that team would be out of the tournament if the season ended today. These are just the biggest movers in the past seven days.
