Guess a lot of people here expected this team to score 60 to 70 points at Chapel Hill. Understand that WF had 45 in the 3rd quarter, but that doesn't mean that the scoring was going to continue at that rate in the 4th quarter "with the right play calls". The other team has highly paid (cheater) coaches and talented players. Greene left the game and UNC stacked the box; they wanted WF to run. FWIW, if WF had called a majority of run plays and gotten stuffed, a lot of Monday Morning QBs here would've lamented how WF got too conservative and should've kept throwing the ball.
Maybe, if WF runs the ball more in the 4th quarter (or throws to the TE more), WF moves the ball better, but maybe not. Clawson and staff understand game situations and opponent weaknesses. UNC left themselves vulnerable to the pass in the 4th quarter, and WF tried to take advantage, but without some of WF's offensive talent available, the offense stalled. This generally happens in most games as the opponent adjusts. Sam Hartman and staff can make the right reads and call the right plays, and sometimes, the opponent makes a play or the receiver drops the pass or runs a bad route.
Just find it remarkable that WF scores 53 points and gains 606 yards, while losing their dominant outside receiver for the 4th quarter, and there's a prevailing notion that offensive play calling or scheme cost them the game. The offense was the only reason WF was in the game; If WF had Duke's offense or VT's offense, the Deacs would've lost 28. WF didn't score 45 points in the first 40 minutes of the game by accident, but WF schemed how to exploit UNC and took advantage. Injuries and adjustments took away that advantage, and unfortunately, the defense (particularly the depleted back 7) could not hang on.
