Jon Embree and the Colorado staff have studied Stanford's Andrew Luck and USC's Matt Barkley recently.
The film of Arizona quarterback Nick Foles was just as unsettling.
"One thing that jumps out at me is how accurate he is throwing the deep ball," Embree said. "He throws the deep ball real well."
And the Buffs (1-9), who host the struggling Wildcats (2-7) on Saturday at Folsom Field in a battle for the Pac-12 basement, struggle to defend the deep pass.
"It's a great matchup, right?" Embree said. "We have to be better at mixing coverages and just be better at playing it. Sometimes it's just finding the ball, sometimes it's our technique at the line of scrimmage."
If there is a coach who should know Foles' tendencies it's CU defensive coordinator Greg Brown, who was the secondary coach at Arizona last season.
The Buffs, who have allowed 8.1 yards per pass attempt and 28 passing touchdowns this season, will also benefit from the return of sophomore cornerbacks Parker Orms and Paul Vigo from suspension.
Orms was a starter early in the season and led the Buffs with 11 tackles and two third-down stops in the team's lone win against Colorado State.
"This probably helped him from the standpoint of he was dinged up with a knee and a hamstring and a calf and all that," Embree said. "(The suspension) may have actually helped him to have this time off to heal."
Vigo and Orms both practiced last week. Without getting into specifics about why they were suspended, the young players said they have learned from the experience.
"I think we deserved what we got and I think it will make me a stronger person and athlete," Orms said.
Orms and Vigo were suspended prior to the Stanford game on Oct. 8.
Penn State connection
The son of first-year CU quarterbacks coach Rip Scherer is a junior wide receiver at Penn State.
Ryan Scherer's position coach, Mike McQueary, is one of the key figures in the shocking case against former Nittany Lions defensive coordinator Jerry Sandusky, who has been indicted on 40 counts of sexual abuse.
Prosecutors allege Penn State administrators ignored a 2002 report from McQueary, a graduate assistant at the time, that he saw Sandusky having sex with a young boy in a locker room shower.
Ryan Scherer has two catches this season for 19 yards.
Finally, the Buffs' schedule is getting easier and the injury list is getting shorter.
Wide receiver Kyle Cefalo (knee), out since Oct. 15, and inside linebacker Brady Daigh (wrist), hurt on the second snap against USC, are both probable for Saturday's game.
Senior cornerback Brian Lockridge (ankle) could be available to play in his final home game. He was injured against Washington State after making the switch from running back.
There is also a chance that safties Anthony Perkins (ankle), Ray Polk (concussion) and Kyle Washington (concussion) could be available.
Wide receiver Logan Gray (leg) is listed as day to day.
Saturday is “Senior Day” and Embree has asked fans to arrive early to help celebrate the Buffs' seniors. CU said Tuesday that the ceremony to honor the class will begin approximately at 12:10 p.m. ... CU is 16-7 on "Senior Day" dating back to 1988. All seven of those losses were to Nebraska. ... Pac-12 coaches will wear a special patch on their game day shirts this week to honor the 70th anniversary of the Tuskegee Airmen, the first unit of African-American military pilots who flew in World War II. ... This is Arizona's first visit to Boulder since the Wildcats pulled out a 24-21 victory over the Buffs in 1986.
