Between coaches, it didn't matter. Meyer already had his mad on for being embarrassed and denied the NC game. His meeting at midfield following the game was vintage Meyer. As a winner, he'll have a cup of coffee with you at midfield, but as a loser he'd be called for illegal motion since he wasn't set for a second. From a public perception, pushing for the score would have been viewed as more of a shot. We usually don't do that. The only exception that comes to mind was Greg's pass last year to Maze in the aubrun game. It wasn't designed, it was just there for the taking and he took it.
Saban operated throughout the second half, and particularly the fourth quarter, in the same manner he has all year long: get a lead, get their D tired, and keep the clock moving. I believe we threw four passes in the third quarter and just one in the fourth (on the failed PAT). When the game is in hand, Saban takes the least risk in terms of the potential for injury or turnovers. He doesn't go for the flash or style points. Once he got the last first down and could run it out with two more plays taking a knee, he did it.
Taking a knee is smart on a number of fronts, but the overriding issue is the injury potential. First, if Roy had taken a helmet to a knee or re-injured his neck, we'd be denied the two back set that has worked very well for us recently. Second, several of the FL players knew they were playing their last football and were taking shots, even on the kneeldowns. It's best to stand there, thank them for showing up and making the game official, and share that moment of watching the clock drain.
