Houston shot just 38% in the first half, but had nine offensive rebounds and scored nine second-chance points. The Cougars lead the American Conference in rebounding margin, turnover margin and steals. Houston shot just 35% from the field, including 19% on 3-pointers (4 of 21) and were unable to overwhelm Tulsa with their physicality, as they have most opponents.
