Down in Dove Valley, newly minted Broncos left guard Alex Palczewski’s locker sits directly across from Garett Bolles. And for a 26-year-old who profiles as a tackle and says his last time playing on the left side of the O-line was the “Obama administration,” there may not be a better mentor in the NFL than the 33-year-old Bolles.

“It’s just how much of a professional he is — like, he just takes care of himself in all facets, physically, mentally,” Palczewski said of Bolles. “Puts himself in the best positions to succeed.”

Bolles has succeeded in one facet better than any other tackle in the NFL this year. He has stared down some edge warriors the past couple of weeks, including the Giants’ Brian Burns and Abdul Carter in Week 7, and not allowed a single pressure since Week 6. On the year, he’s allowed a quarterback pressure on just .09% of his total snaps. That’s best in the league among all tackles with 300-plus snaps, according to Pro Football Focus.

“I always knew my better football was always ahead of me,” Bolles told The Post. “The older I get, I just get more comfortable, and more calm, and more composed. And I knew that was going to happen, because that’s just the type of player that I am.”

Bolles, the longest-tenured Bronco on this current roster, wants the NFL’s inaugural Protector of the Year award. And he’s been the best protector in the NFL through seven weeks. This weekend’s trip to Houston, though, brings a pass-blocking challenge like few others on the Broncos’ schedule.

There aren’t many edge duos in the league that can hold a candle to the Broncos’ speed-rush pairing of Nik Bonitto and Jonathon Cooper. The Texans’ Will Anderson and Danielle Hunter, though, are on that level. Third-year rusher Anderson sits at fifth in the NFL in total pressures (36). Ten-year veteran Hunter hasn’t quite been playing at his normal five-time Pro Bowl level, but he still has four sacks through seven games.

“They’re extremely fast,” Broncos head coach Sean Payton said of Houston’s defense. “And the edges, man, when you look at Danielle Hunter, and — both of these edge players, with wide techniques, are problems.”

That speed is the most pressing problem. The 6-foot-5, 300-pound Bolles and right-tackle-mate Mike McGlinchey were both first-round picks due to their athleticism; they now are going head-to-head with the quickest group of pass-rushers in the league. The Texans rank just 21st in the NFL in total pressures (82), but first among all teams in average time to pressure (2.64 seconds).

Ultimately, this allows Texans defensive coordinator Matt Burke to live in heavy doses of base personnel and four-man rushes without having to blitz much. Teams have attacked Houston quickly: The Texans surrender more yardage per game on throws under 2.5 seconds than over.

The Broncos blew the brakes off the Cowboys last week, and got quarterback Bo Nix in rhythm, because of an offensive line that often gave Nix a comical amount of time to throw. They’ll need a continued superhuman effort from Bolles this week, and the line around him, to give Nix time to go through progressions against a stingy Texans secondary.

“I say this respectfully, it’s not there’s a multitude of things,” Payton said of his impression of Houston’s defense. “But the things they do, they do exceptionally well.”
