Mike Munchak was jazzed enough with the game tape. But when Dalton Risner, unprompted, told him what a pleasure it was to talk shop with the No. 8 pick in the 1982 NFL draft, the Broncos’ new offensive line coach knew right away that this was a kid who didn’t skimp on his homework.

“I think he was definitely impressed,” Risner, the Wiggins native and former All-American offensive lineman at Kansas State told The Post of his recent visit to Dove Valley. “He didn’t say anything. But he gave me a smile.

“With the Broncos staff, I didn’t just say, ‘I’m a fan.’ I could tell you a fact about every one of those coaches. I hope they were impressed with what I did. I think it went great.”

The 6-foot-5, 312-pound Risner, who spent Monday meeting with Washington Redskins officials, gushed about his recent tour and interview at the Broncos’ headquarters, and how stoked he was to get an up close look at the team he grew up rooting for on the plains of Morgan County.

“Just for me to be able to be at the Broncos’ facility, a team that I watched growing up — I walked by Joe Flacco and the guys in the locker room,” Risner recalled. “And to sit down and talk to (general manager) Mr. (John) Elway and to talk with Coach Munchak and Coach (Vic) Fangio, that whole staff, it was just a blessing. I was beaming ear-to-ear.”

Some offensive line coach is going to beaming, too, if they get the chance to choose Risner. The leading draftniks peg the former K-State standout as being taken anywhere from late in the first round to early in the third. NFL.com analyst Charles Davis recently projected the tackle being snapped up by New England at pick No. 32; while the site’s Lance Zierlein tapped the Wiggins native to Oakland at No. 27.

NFL.com rates Risner as the third-best tackle prospect available, with a 6.03 grade (out of 10) that projects him as someone who “should be an instant starter” in the league. CBSSports.com lists the Coloradoan as the No. 8 offensive lineman on the board but the 33rd-best pick overall.

Risner said he’d love a chance to learn under the tutelage of Munchak, a Pro Football Hall of Fame inductee and a nine-time Pro Bowl selection who joined the Broncos in January as line coach after holding the same position over the previous five seasons with Pittsburgh.

“He’s amazing at his job,” Risner said. “He’s a legend among offensive linemen. Not only him, but (assistant offensive line coach) Christopher Kuper … we talked ball, man, it was awesome.

“I think it was a blast to show them I understand the game of football and what I bring to the table. It was awesome to look back with those guys and have them break down the good things I did and the bad things I did and where they see me playing in the future.”

Risner, who started at both center and tackle at various points in his college career, said Elway, Fangio and Munchak seemed to be impressed with his ability to play any position along the line. Elway last month made Ja’Wuan James the league’s highest-paid right tackle (four years, up to $52 million) by signing him away from Miami. Starting left tackle Garett Bolles, meanwhile, is heading into the third season of a four-year, $11-million rookie contract.
