"COVELLI CENTER DEBUT
For the unaware: This game will be played at the Covelli Center instead of the Schottenstein Center. Why? Hockey games this weekend. It's the only game set to tip off at the Covelli Center this season, though it's an interesting venue given the lack of fans. It might, in fact, feel like a more normal arena since it's far less cavernous than the Schott."
