There are two new significant rule changes in college basketball this year. In the men's game, a defensive player will not be allowed to touch a player with the ball facing the basket. In the women's game, there will be a ten second timeline (halfcourt).
The men's game will be dramatically effected and there will be more offense and more zone defenses. (Where's Jim Boeheim when you need him?) Foul trouble will be more common and more foul shots will be taken. Look for games to be longer.
The change in the women's game will allow teams to press more and use their quickness to create problems for opponents. Look for more excitement in the women's game with the press.
