People gotta get out of this mindset that their offense is a gimmick. ****, if it's a gimmick, I'll take it since it's productive as all get out and rarely turns the ball over.
This is the modern day offense. Confuse the defense with all kinds of sets, misdirection, counters, and get the ball in the hands of your playmakers as soon as possible.
It also preys on the biggest weakness in all of football. The crusty old dinosaurs that largely dominate the defensive coaching ranks. They are still living in a decade or two past where they're terrified of the bomb down the field with single coverage and their corner or safety getting roasted. They see yards put up in big chunks and in their mind, they can't be having that.
All the while, this offense and others like it completely negate the best pass rushes by getting the ball out quick. We can't get there so the crusty dinosaurs bring more players up, help with safeties over the top and what you're left with is a ton of options underneath. So the new style OC'ers will take what they're given, get the ball out while in the gun (***** that under the center bs), before anyone gets close to your accurate as **** QB.
It isn't a gimmick, in particular when you've got dynamic receivers, more physical than they've ever been, and then you hit them over the top with your accurate QB.
That's all Clemson does. Toss elite backs into the mix, good luck defending these guys unless you've got an all world set of DB's who you can leave on an island.
