Rebounding, 3s will be big keys

There are two terrific national semifinals on tap. Here's a look at the opener:

Ohio State vs. Georgetown (Sat., 6:07 ET)
Both teams have a great mix of veterans and young players, both have looked dominant at times, and both have come within an eyelash of getting bounced from the tournament. Each team has an outstanding big man who is a true center, and each has a hot young coach. It is fitting that they would play each other in the Final Four for a trip to the title game.

Ohio State personnel
The Buckeyes are led by senior Ron Lewis and junior Jamar Butler because of their experience, but on the floor, freshman point guard Mike Conley Jr. is the man in charge. Conley (11.0 ppg, 6.1 apg) is a special player who has an extraordinary feel for the game. An outstanding athlete, Conley plays with great pace, but has another gear that he can rely upon, and he makes unusually good decisions. Conley is indispensable, because he impacts the game with points, steals, assists and his control of tempo.
