The 8.4 wins per season have been nice, no doubt. I'm not discounting what we've accomplished the past decade. But would we have done even better if we had an offense that was more consistently effective instead of just playing to "stay out of the way"? That's why I think one of the earlier posters mentioned that the offense is "holding us back". With the exception of 2002, our best offenses have only sniffed the Top-25.
If the defense can consistently be Top-10 nationally, then why does the offense have so much trouble finishing better than middle of the pack? I would even be glad to see us around Top-25 most years. I'm not asking our offense to be world beaters, just effective.
While 8.4 wins may be "good enough", I personally believe we would be able to do even better if our offense was putting more points on the board. 2002 for example, is an example of what I believe we could be if we had a more consistent offense.
Our offense reminds me sometimes of baseball where you squander good pitching because your team can't hit, and you lose 2-1. If you could have scratched out 4 or 5 runs you win. You don't have to score 10.
Is it too much to ask for the offense to take some burden off the defense?
