The Boise State Broncos have bought into head coach Bryan Harsin. It's been that way since he took over the team in 2014, and the Broncos are feeling good entering the third week of the college football season.

Boise State came in at No. 22 in the latest AP Poll following its wins against Florida State and Marshall. The Broncos have yet to allow a second-half point this season and the mix of a powerful Broncos defense and a rejuvenated offense played a significant role in the team's early success. It's all a byproduct of the system Harsin has implemented at Boise State.

Former Boise State head coach and current CBS College Football Analyst Houston Nutt credits Harsin for finding ways to adapt against the team's difficult competition. He joined "The D.A. Show" to talk about Harsin's impact on the Boise State program.

"I've had the privilege to coach Bryan Harsin," Nutt said. "He was the backup for me when I was at Boise State and I can tell you firsthand; first of all nothing but integrity, character, leader, studies film from daylight to exhaustion and he cares about his players. You can see it. The way he treats his players, the way he demands effort and attitude is just absolutely phenomenal. They follow this guy and you can see it. They've been following him ever since he was named head coach. He has the blue print on how to get things done. He does it with excellent teaching."

Quarterback Hank Bachmeier is one of the many Boise State players to elevate themselves under Harsin's tutelage. Bachmeier was dubbed as Brett Rypien's replacement after the latter signed with the Denver Broncos. Rypien left a large void in the team's offense, throwing for 3,705 yards in his final season but Bachmeier is proving himself this season and consider Nutt as one of those who were surprised by the freshman.

"I was expecting such a drop off," Nutt admitted. "When you lose Brett Rypien, you think 'ok, you're going to have to work your way in here with the next guy. You know he's not going to be at that level.' Then all of a sudden, you look up and this guy is throwing with accuracy, getting them out of the wrong play and getting them into the right play. You feel so good about that."

Boise State's defense help mount the 18-point comeback against the Seminoles on Aug. 31. They swarmed Florida State running back Cam Akers, converting on his lone fumble with a touchdown, and secured ideal field position for the team to march 60 yards to secure the win.

"When you're 31-13 and you're down, man it takes backbone and it takes a defense to be able to get the ball back to your offense," Nutt said. "That's where you've got to give Bryan Harsin and his staff so much credit to go on the road and win a game like that. It builds so much confidence."
