Prior to this offseason, it had been four years since Broncos veteran offensive lineman Graham Glasgow worked regularly at center, starting 16 games for the Detroit Lions in 2018.

That foundation of knowledge at the position and the overall experience of starting 78 NFL games has benefited Glasgow in his new role as a multi-spot backup.

Glasgow played 51 snaps against Dallas and 31 snaps at Buffalo, working at guard and center. He started at center Saturday night against Minnesota.

“There is always stuff to get better at, but as a whole, I think it’s gone off without a hitch,” he said.

Glasgow, 30, missed the final eight games of last year with a broken ankle. He was limited in the offseason program so there was rust to be shed.

“I think the majority of it got knocked off in practice,” he said. “But I hadn’t taken a ton of consecutive reps in practice so having a 10- or 12-play drive (against the Bills) was different, but that (endurance) came back pretty quickly.”

Glasgow’s $3.1 million base salary became guaranteed in March and he has play-time incentives starting at $250,000 for 50% of the Broncos’ offensive snaps. The Broncos are committed to Dalton Risner at left guard, Lloyd Cushenberry at center and Quinn Meinerz at right guard. That makes Glasgow an expensive-but-important swing backup.

Glasgow has snapped to all three Broncos quarterbacks — Russell Wilson in practice earlier this month when Cushenberry (knee) was rested and to Josh Johnson and Brett Rypien in the games.

“I definitely got unfamiliar with it,” Glasgow said of center. “But it’s almost kind of like riding a bike. There is stuff you pick up and there is some stuff that may take you a little bit of time to get back into. The communication is fine, but it’s just the rhythm of the different quarterbacks and you have to start the play (with the snap).”

Managing Gregory. Outside linebacker Randy Gregory (shoulder) practiced three times during the week after being activated from the physically unable to perform list.

“(Gregory is) what we thought he would be — explosive athlete and he’s going to help us a lot,” defensive coordinator Ejiro Evero said.

There was no need for the Broncos to rush Gregory back to get preseason work against Minnesota.

“The only thing that matters is Week 1 (at Seattle),” coach Nathaniel Hackett said. “We want him ready to rock on Week 1.”

Anderson competing. Broncos right tackle Calvin Anderson was the only potential Week 1 starter to play in all three preseason games. He started at left tackle against the Vikings.

“I’m actually happy I’m playing,” he said after a practice last week. “We’re getting more reps. I’ve only played in five games and the idea is to get as many reps as I can.”

Anderson played a combined 41 snaps against Dallas and Buffalo.

Asked if he was disappointed to be playing in the preseason, Anderson said: “Absolutely not. I knew coming in that, one, it would be a competition from the beginning, and two, I would have to show on the field in the games that I can play.”

Billy Turner was activated off the physically unable to perform list Monday, but didn’t take regular team work during the four practices. Cam Fleming received some first-team reps.

On the road. General manager George Paton holds daily roster meetings with a group that includes his pro scouts. But his college scouts are already traveling the country to evaluate players.

“For college scouts, this is a really good time to get out (to campuses) in early August so we stopped bringing them to training camp,” Paton told The Denver Post. “Now is when you get really good background (from college programs) before the games start.”

Having a say. The Broncos will begin roster deliberations Sunday morning and Paton said the coordinators will be a part of the process. Special teams coordinator Dwayne Stukes will provide his views.

“I don’t know how much of a voice I’ll have, but I am going to express my opinion,” he said. “If we want to get to being one of the elite (special teams) units in the NFL, we need to keep quality guys around who can play at a high level. I’m going to tell (Paton) my opinion. I’m going to tell Coach Hackett my opinion. Hopefully (I) have some influence on some of those back-end roster guys, but I can’t promise you that.”
