The obsession with Colorado's defense overlooks their offensive line, which gave up 56 sacks last year. That puts constant pressure on any defense. Miami's defensive turnaround under Mario Cristobal shows identity is built in the trenches first. Colorado's defensive struggles are a symptom, not the root cause. Their 6.8 yards per play allowed is bad, but you can't scheme around getting dominated up front every snap. Until they fix the line, no scheme will work.
