who cares about efficiency, when the other team is playing only to stop the run and leaving receivers with single coverage (not to mention the majority of your passes are roughly 5 yards) you should have a good efficiency rating. When you rank 121 out of 128 in passing that is troublesome. That shows that the coaches aren't throwing the ball because they know they can't succeed at it. Goods teams stop the run and know they can stop the Gophers.
And mocking me about a spiral...... that's kind of important. Ask a WR what kind of a ball they'd rather catch, a spiral or a wobbler, let me know what they say. Also, when you need to drive a ball into a tight window, would you have better success doing that with a spiral or a duck?
