I don't think the offense has changed that much, but the execution has changed a ton. We're an offense that is predicated on being able to keep the defense honest with a QB who can get into space and make plays. But our QB isn't calling his own number often enough. I wasn't keeping a running count, but I only remember a couple times where Barriere called his own number and took off upfield against UND. One was a third down and he went for about 15 yards; another resulted in a TD. We need him to mentally prepare for taking the ball himself when the read is there.
The offense isn't predictable by design, it is predictable because we run the same plays regardless of what the defense presents. We opt for the same variation even if it is the wrong choice based on what the defense shows. That's not a play call, that's execution.
Defensively, we seem to have simplified what we're doing. The first couple of games, we were shifting so much that our DL was often out of position. It seems like we've stopped doing that with regularity. Ultimately, we have LBs who want to fly around, so getting big performances out of the DTs is paramount. When Moore was out, we didn't have enough talent to make that work. With him back... our D was MUCH better. The other thing I notice is how small our DBs are. Any team with big physical receivers is a bad matchup for us.
