I'ts funny that you bring up Oregon and "simpler", and here's why.
Chip Kelley said once while at Oregon that they had four running plays: inside zone, outside zone, counter and draw. That's it.
Conceptually speaking, and in theory, this makes a ton of sense. He said that it allows for the coaches to put the players in an environment where they can be successful because they understand what they have to do. If the players haven't run a play in a critical situation over a thousand times in practice, the play will not be successful.
The concept definitely works, and Oregon has proven that a million times over. Of course, the "4 plays" is an overgeneralization, because there is probably a dozen variations to those four running plays that involve different blocking schemes and what not. But because there's only 4, that allows for the players to understand their role and become a master of the offense that can take on the problems a defense may throw at you.
I think that we proved this also in the 90's with our option. We mastered it. We had masters of the offense run those plays until they got a feel for what it takes to make a simple option play successful.
I caution towards simply saying "we only need 4 running plays!! Why are we running more than 4 running plays!?!?" because as Navy has shown, the concept is not always successful. We didn't have success with the option every single year. Oregon had numerous sluggish games during Chip Kelly's time there.
Personally, I like the direction of our offense. Personally, I would call Oregon "multiple" with a strong emphasis on the running game. A lot like how we are "multiple" with a strong emphasis on the running game.
Last year was tough. Injuries plagued us more than any scheme ever devised. You sure can talk about simplifying an offense, and having the players practice it a thousand times, but that player who practiced it a thousand times is out, and now a player that hasn't practiced it that much. That concept goes out the window. That's why injuries are so huge.
It's also important to have all the right pieces. Air Raid was highly successful at Oklahoma and Texas Tech, but how's it doing at Washington St?
Anyway, I talked a lot, could talk more, especially when we are actually talking football. But I'll shut up now.
