go back and check out what Miami did with the Wildcat.
Something very different than what teams were accustomed to seeing. They were VERY successful in running it for ONE season. Once teams figured it out....they shut it down.
Go back and watch the 1996 Panthers Defense. Dom Capers was running an exotic defensive scheme (gimmick). It was VERY successful until GB showed how to play it. Then it was shut down.
Gimmick offenses and defenses (something no one has seen before) are usually VERY short lived in the NFL. Teams figure them out and they are basically shut down.
There are just as good of coaches in in college as there is in the NFL. Perhaps even better coaches. And they still haven't figured it out.
That is because it is virtually impossible to account for everyone on the field like that.
With the Wildcat you really don't have to account for the receivers so you can bring both safeties up for run support. You don't have that luxury with the read option.
And one other thing. No one runs the spread option offense in the NFL the way it should be ran. Not Was, Sea, SF, or Carolina.
If a team really wanted to run a great spread option type offense, all they have to do is watch Peyton Manning's offense. Quick or no huddles, get to the line of scrimmage, make the defense show their hand, make adjustment according to what defense is doing. Only difference is that you have a QB that the defense also has to account for. It makes it virtually unstoppable. Granted in order for it to actually work in the NFL you have to have a QB that can also throw the ball. You couldn't get away with it in the NFL if the QB was just an athlete.
I don't think you can now call that offense a gimmick. It is mainstream in college now and is making its way to the NFL.
