MORGANTOWN — Dan Jennings, a true freshman forward, pulled down 12 rebounds, scored nine points, and blocked three shots in 16 minutes played in his first collegiate game Sunday, an 83-60 West Virginia victory against Loyola University (Md.) The 12 rebounds were more than any other true freshman in a season opener in the history of WVU men’s basketball. The 6-foot-8, 260-pound Staten Island, N.Y. native’s performance left a lot of people wondering aloud: What could this kid do if he had even a partial clue of what he was supposed to be doing out there? Even Jennings couldn’t answer it, instead offering questions himself. ‘‘I don’t think I played as good as I could have played,’’ he said. ‘‘What if I knew the offense? What if I knew where to be in the motion?’’ When he figures it out ... ‘‘I feel sorry for the people playing against us,’’ West Virginia forward Da’Sean Butler said. In the meantime, Jennings makes up for his lack of knowledge — and make no mistake, there isn’t a true freshman in the country that has it all down at the moment — by crashing the boards and making bricks off the back of the iron look like planned alley-oop passes. It happened three times against Loyola on Sunday. ‘‘Just shoot it,’’ he said. ‘‘A shot is like a pass. I’ve got to block shots and attack the offensive boards at all times. That’s better than scoring.
