If Cody Green is playing QB, I don't see how we could possibly win. Colorado is good against the run and will load the box. We'll be lucky to score in double-digits.
Yes, CU is good against the run. But that's mostly because of their speed. They play a nickel D (I think) that depends heavily on guys swarming to the ball. Obviously the NU offense has seen this before and experienced what happens against fast defenses when we use the zone read as opposed to a north-south attack. Our zone read does not work nearly as well when we're running sideline to sideline. But, if we attack the heart of their D by running right at it, we have success because we neutralize their speed.
Hopefully our offensive game plan consists of heavy doses of this north-south running game. Whether Green or Martinez is QB, that's the attack that will work.
