PITTSBURGH — Ben Roethlisberger might not just be at the controls of the NFL’s most dynamic offense, but perhaps its most democratic.

When the Pittsburgh Steelers quarterback is in the pocket — and sometimes when he’s not — he doesn’t do a quick rundown of each option’s resume.

He searches for the best matchup and he fires. That’s pretty much it.

“I’ve been in the league long enough to know every single receiver is open on every single play,” Roethlisberger said with a laugh.

Even when they’re not, though that hasn’t been the case often during Pittsburgh’s 2-0 start, a testament to Roethlisberger’s rising confidence in what may be the league’s best set of weapons even with Martavis Bryant sitting out the entire season because of a violation of the NFL’s substance abuse policy.

The proof is in the box score. Roethlisberger spread his 19 completions in last Sunday’s 24-16 victory over Cincinnati to nine players.

When the Bengals made it clear their focus was slowing down the seemingly unstoppable Antonio Brown, Roethlisberger stretched the field by going deep to Sammie Coates and having 6-foot-7 Jesse James and 6-4 Xavier Grimble basically posting up in the red zone .

Even backup running back Fitzgerald Toussaint and blocking tight end David Johnson got at least one ball their way.

“Are they going to get their yards? Yeah they’re going to get their yards,” said Philadelphia coach Doug Pederson, whose team hosts Pittsburgh on Sunday.

“They’re too good not to get them and Ben’s too good to not get the ball to them. He’s utilizing a lot of those guys and he’s getting the ball out of his hands fast.”

And to think Markus Wheaton — the No. 2 receiver — hasn’t played a snap yet while nursing a sprained shoulder and Le’Veon Bell — is out one more week while serving a drug suspension.

“Everybody’s got a different aspect they bring to the game,” Coates said. “That’s what’s so good about our group.”

One in which Coates is doing a pretty good job filling the void as the deep threat while Bryant tries to get his career back on track.

A fourth-round pick in the 2015 draft, Coates spent the majority of his rookie season watching from the sideline in sweatpants after failing to make the active roster on game days. It was a humbling experience being healthy, but deemed not essential.

“When you first get in the league, you’ve got a lot to learn,” Coates said. “You’ve got to compete.”

And earn Roethlisberger’s trust too. Their budding chemistry was on full display against Cincinnati, when Roethlisberger escaped pressure and rolled to his left before dropping a rainbow that Coates hauled in over his shoulder for a 44-yard gain .

A year ago, Coates probably doesn’t turn upfield almost instinctively at the site of his quarterback in trouble.

Not anymore.
