When West Virginia football coach Neal Brown spoke at the Big 12 Media Days Wednesday, the first questions he handled centered on his offense. Of course, a lot is expected from the offense this year, which is returning nine starters from a squad that averaged 31.5 points per game last season. Brown agreed, saying “We do have a big hole to fill in Zach Frazier,” Brown, who is beginning his sixth season as WVU’s head coach,added. “Zach got drafted by the Steelers and is going to be the Steelers’ center of the future. He set the tone for us, and he really changed the trajectory of our program just by how he worked. But we do return six of our top eight guys there (in the offensive line).
