In the summer of 2017, the NCAA added more major changes. Prior to the newest addition, all players needed to stop play upon whistle of the referee. Play was resumed upon another whistle or continuation by self-start. Now, free movement has been implemented, meaning upon the whistle for a foul, play does not stop unless for halftime or the end of the game–this is similar to soccer. Also, the defense is now allowed to run through the crease of the lacrosse goal. For the draw now only 3 players, instead of 5 players, will be allowed into the midfield area until possession has been established. Lastly, you have to move out of the eight diagonally after a penalty has been called.
