So I should stop basing my expectations on what Harbaugh did in SF, but we should hold Chip's lack of NFL success against him?
I feel like we've had this discussion like 10 times already but Chip's O is more than just tempo, he was putting up numbers in the FCS even before he adopted that after reading Gus's book. The lack of further evolution of his O in the league is a bit alarming, but in his defense the lack of a mobile QB and the rule changes are not going to hamstring him in CFB like they did in the NFL.
Yes, the D is built to play with leads and compliment the O. They might run into some problems against a team like Stanford if the O isn't clicking, but against everyone else they should be fine. He's going to have access to much better athletes in Westwood than he did in Eugene.
Unlike on O, you need athletes to be good on D, unless your going to run something ultra exotic.
