I think one of the biggest issues with our offense is lack of identity. What is the one thing you do well? You need 5 yards, what is the play that almost always gets it? We haven't really had that under Beck. You just keep hearing that we want to be multiple. Multiple. Jack of all trades, master of none.
See I think McKewon's excellent analysis suggests the exact opposite. The dominant teams, which presumably have this offensive "identity" we crave, are efficient at both running and passing the ball. When it's 3rd and 5 they don't have one play that almost always gets it. They have a few to choose from, because every defense has film of every game. Their offensive success isn't from creating an identity, unless that identity is good athletes who are mentally prepared and able to execute a diverse play selection. The Top 10 is full of teams who are master of all trades. That's where excellence comes from.
I think we have a promising offense and should have a solid running game. McKewon's point seems to be that memories of Nebraska's impressive running attack are pretty selective, and dreams of just ramming Abdullah down the opponent's throat might be misguided.
