If Carnes knows 5 pass plays out of our basic pistol set that would be 11 personnel for those keeping track at home then what difference does it make who lines up where? It doesn't make a shred of difference to us but it could make the defense hesitate for just that split sceond which could result in a big play or even cause them burn a timeout early in the game. There were certainly numerous instances last season where our defense had to burn timeouts because the offense was doing something unexpected.
I think you're ignoring something very basic here. Running a play isn't as simple as saying you go here, you go here, run the play. It takes repetition, hours of practice and hours film study to get good at your job. Do we really want to devote hours each week (which is what it would take) to introducing multiple different fluke/trick plays for every game? It's just so unreasonable. It will result in false starts, not having 7 players on the line, timeouts, you name it. Remember back to '08, when we had the trick field goal play and the holder would throw it over his shoulder? We did it twice - once for a first down, and once for a touchdown awarded to the other team. Trick plays are dicey, and need to be carefully planned/coordinated.
An exampled that worked for us - against Iowa, we had Martinez get the ball, fake a run, and then he did a little jump pass to a wide open Reed. Required no personnel changes and nothing fancy. Just a twist on the basic concept of play action.
I'm not saying fluke/trick plays aren't beneficial - they can be game changers. But they need to be things that make sense. Cotton at FB doesn't. Martinez at WR with Carnes at quarterback doesn't.
When Pelini is talking about getting new looks, he isn't talking about our opponent lining the center up at wide receiver. Sure, there are some personnel things, but most of what he's talking about are formations - different ways the opponents line up their base personnel to throw the defense off.
I understand what you're saying, but trick plays need to be an extremely small percentage of what you do as a football team. You're somewhat making it seem like it should be a staple of what we do, and it isn't a staple of any team. Even Spurrier's antics are only once or twice a game at most, and he's outside the norm.
