If you've watched Petrino closely, on how he's handled Lamar, it's clear he agrees with what you have said, because he has spent countless hours training him to run theses types of sets. It's all about reading defenses, going through progressions, and selecting the right options. It's about poise, footwork, and getting the ball out, delivering it on-time and accurately. And with his extreme running skill, it's also about knowing when to run, and when to stay in the pocket and beat them with your arm.
In short, it's about being efficient, and minimizing mistakes that stop drives. Once he learns to do that in a fairly consistent manner, we become unstoppable because we are so explosive. But we aren't there yet.
The FSU game showed us what we are capable of, as we scored on 60% of our possessions...all TDs. But for the most part, in the other 5 games, we have been far less efficient than that (scoring on less than 50% of our possessions, with several red zone trips over the last three games ending in 3 points or less). Our explosiveness and high number of possessions per game have allowed us to still put up big points, except in the Duke game. In the Duke game, we were only slightly less efficient offensively than we have been all season (scored on 4 of 9 possessions, 3 of which were Tds), but scored far less points due to only getting 9 possessions.
Increase our efficiency on offense to the level we executed at against FSU, and we're a national contender for the title.
