 Defensively, what they couldn't do was tackle anybody. They're one of the worst rush defenses in all of college football. So those two reasons right there really led to Colorado just falling off a cliff at the end of the year and going 1-8 in their final nine games. So in order for me to believe a year two turnaround is coming for the Buffs, you have to first sell me that improvement on the offensive and defensive lines is happening.
