Our use of the 3/4 has decreased so much, we're already moving in the direction of it's being our "base defense" in name only. We're also moving in the direction of lighter, more mobile players. Of course, one trade-off is the effect on tackling...
We're already there. I've tracked it over the last 4 seasons and we are only in the 3-4 between 20-25% of the time. the reality is our base is nickel. Our second most used package is dime.
Discussions like this will ask:
is the 3-4 outdated? Should we change? the answer is we already did. We even have 3 different groupings for our nickel packages now.
The next question is: should we have hybrid players that are more versatile? last I looked that's exactly what the Star and Money positions we use are. Te OLB spots also have a lot more versatility in what they are expected to do now. Even though we have not added a new 'position', we definitely have added a new LB role to the mix. We most often fill it with an OLB, but sometimes have used an ILB.
Then it's about the coverage scheme, but the reality there is we use EVERY coverage scheme imaginable. that's the only one I think is debatable, as I could see there being some benefit to not having quite as many options to reduce the chances for a miscommunication.
That could be the crux of the whole issue, really. Regardless of the alignment (3-4, 4-3, 3-3, 4-2, or 2-4) our defense is pretty complicated. Some past players have said it's more complicated than the NFL defenses they go on to play in. maybe it's a bit to complex, and that causes some of the misses we see with players taking the wrong assignments, etc...
