Correct, and for all the hand-wringing about Limegrover's playcalling and how the Gophers have only beaten "bad" teams, the OL issues seem to be glossed over. People might be tired of hearing the "youth" excuse, but those of us who coach or have coached know that it is the truth, pure and simple, and cannot be underestimated regardless of how much people might want to find a scapegoat.
If you go back and watch the games, you will see that the Gophers have beaten teams who they could move around up front. When they control the line of scrimmage, they run the ball. When they run the ball, it opens up passing lanes because the defense has to walk a player up to stop the run. Far too often, people think that a team can just go to the pass because the run is taken away. The reality is that the run (or the threat of the run), in nearly every offense, sets up the pass. Even the Mike Leach/June Jones offenses have easy audibles meant to exploit defenses that try to get too cute to stop the pass. They just check to the run, get a hat on a hat along the line, break off a 10 yard gain, and the defense has to move a LB back inside.
The problem with the Gopher offense right now is that good, mature defenses do not need to walk anyone else into the box to stop the run; they are able to do it with only their interior six or seven, thus allowing them to keep an extra defender back to stop the pass as well. This is not the case against younger or weaker teams.
Overall, this one reason is why I am optimistic about the direction things are going. If this is what the offense looked like with an experienced OL, it would be cause for concern. I, however, LOVE that they are beating the "bad" teams with a ridiculously young OL. The hope is that next year, the OL will be able to move defenses around a little more. When that happens and defenses have to adjust, it will open everything else up. I am pretty excited to see how it all works out, and so the development of the OL next year (NOT in the bowl game) will determine how confident I am in things going forward.
