Defensive coordinator Willie Martinez said his team began to do a better job against the play in the second half.
"But I'm not going to sit here and say we were 100 percent at it," he said. "You have to defend all the plays. You can't just sit on that one play."
Martinez credited Jackson with leading the Colorado offense. The junior had his best game by far in first-year head coach Dan Hawkins' offense, throwing for 140 yards on 14-for-26 passing. That topped his passing total for the first three games combined.
"There were times in that game where that kid made plays with blitzing guys coming right at him," Martinez said.
