Frank Crum never caught a pass or scored a touchdown in his football life.

That all changed Saturday in a Broncos divisional round playoff overtime victory, 33-30, over the Bills at Empower Field. Crum — a 6-foot-7 and 315-pound offensive tackle — hauled in a short touchdown pass in the first quarter to help Denver advance to the AFC Championship Game.

“That’s an O-lineman’s dream,” Crum said in the postgame locker room. “To score a touchdown.”

The idea was hatched last week at practice when ex-Broncos assistant coach John Morton — fired after one season as the Lions offensive coordinator — rejoined Denver’s staff as a playoff consultant.

Coach Sean Payton said Detroit ran the same play against Buffalo in the regular season last year, and the Broncos drew it up for Crum as the sixth “jumbo” offensive lineman. Quarterback Bo Nix went under center, faked a handoff to running back RJ Harvey and rolled out to his right. Crum initially engaged a blocker before releasing on a quick route.

Nix delivered a strike to Crum, and he rumbled toward the goal line. Bills cornerback Cam Lewis attempted to take Crum out at his knees. But he simply flipped over Lewis and into the end zone for a 7-yard touchdown.

“They have a tendency to play more man when you’re in jumbo,” Payton said. “So, a little short motion bumps — who’s covering who — and that’s one of those ‘Rudy’ plays. Your whole team goes crazy when that happens. (Crum) is very athletic, and sometimes you don’t get the look you want. We got the exact same look Detroit got. Ours scored just like three seconds quicker. Their guy took a while to get in.”

Broncos offensive linemen mobbed Crum on the field in celebration.

“Fantastic, man,” left tackle Garett Bolles said. “It was awesome, Frank scoring that touchdown. We put it in earlier this week. We executed it and it was just amazing to watch a big man score a touchdown. It’s always fun.”

Right tackle Mike McGlinchey added, “That was the coolest thing ever. We’ve been working on that play all week. Frank is a hell of an athlete, man. He can boogie out there when he gets going. He’s like a diesel truck.”

Crum focused on his practice execution when the play came into the Broncos huddle. It happened so fast that he didn’t have time to overthink. His success was especially important with two starting wide receivers exiting on Saturday due to injuries — Pat Bryant (concussion) and Troy Franklin (hamstring).

“I obviously trust my hands,” Crum said. “I’m not on the jugs every day or running routes. But they work.”

Teammates like tight end Evan Engram always envisioned Crum’s potential beyond the offensive line.

“I’ve been recruiting Frank all season to get in that tight end room,” Engram said. “So, I’m just glad that it’s finally coming to fruition. It was cool. It was a play that we had circled all week. We were hoping to get that one off. Executed perfectly. We’ll review the celebration. We’ll work on that for sure.”

Crum is in his second NFL season with the Broncos and went undrafted after a decorated college career at Wyoming. He is a third-generation Cowboy whose father and grandfather both played football in Laramie. Crum grew up cheering for the Broncos.

Payton told reporters in August that three NFL teams called with trade interest in Crum. That buzz should only grow as Crum proves his versatility and athleticism. He is a project player with huge potential at offensive tackle.

“They’ve invested in me,” Crum said. “We knew there was going to be some development coming out of Wyoming. I’m grateful for that and coach Payton believing in me. I’m always looking to improve.”
