What part are you questioning? The D has always averaged around 30 points per game. Could they get better? Yes. I think even Frost said he would like to see it get down to 26 pts per game, but here it has averaged right at about 30. Last week was no exception.
The offense is supposed to be geared to score higher than that, with tempo. Now I understand it has changed to Whipple's offense, but I don't think they have changed the defensive strategy.
I would like to see that change, in fact it made no sense at all to run the high risk / high reward defense all these years when the offense sucked, because you're just giving up way too many points, but so far, we are seeing more of the same.
Those of you blaming the defense are blaming the system more than anything. Do a new system, all for it, but Chins is still running the same D as he was when he got here.
