I'm not sure how you can say he called the same game for both QBs.
Jalen threw 8 passes, Tua 24. There were other differences. But the bottom line is that Jalen simply was not producing well against good defenses. It hurt the running game as well as the passing game. Some of that could possibly be put at Daboll's feet but most of it at the QB's limitations. What else did you want him to call for Jalen ?
In the 2nd half, Bama put the ball in a true Fr. hands not to manage it, but to win the game by throwing 24 times.
The second half was a great performance - a score or easy FG attempt on 6 of 9 possessions, including 5 of the last 6, and the last 4. Each of the last 4 possessions were critical and full of pressure, and Bama's offense delivered (as did the D). It was not perfect, but it was a remarkable, legendary and program changing performance.
