His first pass attempt Saturday was batted down by an opponent, but Klatt quickly regrouped and ended up completing 26-of-33-passes for 371 yards and three touchdowns.
However, before Colorado took firm hold of the game in the second quarter, North Texas came out strong and had the Buffs back on their heels early. And while the Colorado defense came into the game ranked No. 4 in the country in run defense, Mean Green true freshman running back Jamario Thomas ran by the Buffs for 247 yards in the game, the third-best performance by an opposing rusher in CU history.
After Colorado went three-and-out to open the game, North Texas caught the Buffs' defense off-guard on its first possession. Thomas took the hand-off on the second play from scrimmage and ran untouched for a 57-yard touchdown.
The Mean Green reached into its bag of tricks and completed a successful onsides kick to take control at their own 45 after the ensuing kick off. But Colorado kept the gambling North Texas from converting on a fourth-and-5, and took over on downs. Six plays later, Bobby Purify ran in from the 11 for CU's first score.
A personal foul face-mask penalty on CU safety Tyrone Henderson helped set up UNT's next score, another strong run by Thomas, this time for 25 yards through the heart of the Colorado defense.
The Colorado offense answered with a quick five-play, 73-yard scoring drive, which ended with a touchdown when Purify broke free for a 24-yard run.
Cornerback Lorenzo Sims single-handedly stopped what looked like a North Texas scoring drive next when he popped the football loose from UNT's tight end Andy Blount and recovered the ball at the Colorado's 5-yard line.
The Buffs rolled to three-straight unanswered touchdown drives following Sims' fumble recovery. One ended with a two-yard touchdown reception by Joe Klopfenstein, the next with an 11-yard run by Purify. Then, with just under a minute to play in the half, Klatt hooked up with Evan Judge for a 21-yard scoring pass.
Colorado went into the half with a 35-14 lead. Klatt led the first team to 10 points in the third quarter, before the second-team offense took over in the fourth.
Purify finished with 15 rushes for 112 yards, while tight end Joe Klopfenstein led CU with 6 catches for 67 yards, including two touchdowns. Tyrone Henderson paced the defense with 10 tackles, six unassisted.
Colorado moved to 3-0 with the win, and is the only unbeaten team in the Big 12 North.
