Arch Manning's first game of the season did not go as planned. The Texas quarterback struggled badly in the first game of the season, a marquee matchup between the #1 Longhorns and the #3 Ohio State Buckeyes, the defending champions. Ohio State won 14-7.Manning had a poor showing. He was inconsistent for the whole game, completing just 17 of 30 throws. He also had just 170 yards to go with one touchdown and one interception. Ohio State's defense dominated the contest, and the win will put them at #1 when the next ranking drops.Despite a poor performance by the quarterback, his defenders were urging fans to remain calm, as Texas was playing just its first game of the season. Among them was former NFL wide receiver Dez Bryant, who called fans "crazy" for some of the criticism after a single matchup."You sound crazy. One game against the defending national champions. He missed a couple of throws trying to protect the WRs from getting blown up as well. His IQ for the game is sky high; the minor mistakes will be fixed as the season goes on."What's Arch Manning's family tree?
