Honestly the team reminds me a bit of the Ducks in recent years. Not this year obviously. Our offense puts pressure on other teams to play more risky. However our defense is good, so they make people pay when they make mistakes.
The biggest difference IMO is that CU is playing with a bit of old school big 8/12 toughness and physicality. Something the Ducks never did. It is an interesting hybrid that so far has been a ton of fun to watch.
Defensively, what has surprised me is how vanilla Leavitt has been able to go this year. Buffs play a lot of straight up base D. I guess when you've got a 3-man DL that requires all 5 OLs to get blocked and 3 CBs that can all shut down a good Pac-12 WR in man coverage without safety help, you don't have to screw around too much. The cool thing with that, though, is that Leavitt's got the horses to take major risks if he feels that he needs to.
