ENGLEWOOD, Colo. -- There is indeed just one ball to go around, but the Denver Broncos' top two receivers would like to see it come their way a little more.

In what is a small ripple in the Broncos' 2-0 pond, the team's top two passes catchers -- Demaryius Thomas and Emmanuel Sanders -- find themselves in supporting roles occasionally in an offense that has run the ball more (60 times) than it has thrown it (59 attempts). As a result, the two have as many catches combined (17) as Miami Dolphins wide receiver Jarvis Landry has individually to lead the league.

Thomas has nine receptions, behind 40 players in the league, while Sanders has eight receptions. Trevor Siemian, the 24-year-old quarterback who is charged to find the open man as he learns on the job, said he understands.

"It's understandable ... we want to give those guys opportunities to make plays," Siemian said. "Those guys have been awesome ... those guys have been great with me pulling me through ... They know they're getting their touches."

Or as Sanders put it:

"There's some frustration, but it's hard to be frustrated when you’re sitting here 2-0," Sanders said. "I can sit up here and make it all about me and Demaryius, how we're used to having 100-yard games, we're used to scoring touchdowns and we're used to doing this. But we're sitting here 2-0 ... Individually, I would like to have my highlights on ESPN, yeah, I would like to have 100-yard games, be ranked top five, but we're sitting here 2-0 ... I'm waiting for that big game, Demaryius is waiting for that big game -- we know it’s going to come."

Neither Sanders nor Thomas has a touchdown reception in the Broncos' first two games and Sanders hasn't topped 50 yards receiving in a game. In the Broncos' win over the Colts this past Sunday, Sanders had three receptions in the Broncos' first seven plays from scrimmage, then didn't have another catch in the game.

Sanders went as far as to say Wednesday "that at some point if what we're doing isn't working" the Broncos might have to "change" some of their play-calls.

Thomas had five catches against the Colts for 90 yards, a total that included a 44-yard catch-and-run off a screen pass for the Broncos' longest pass play of the season.

But given the $70 million deal the Broncos signed Thomas to last season and the $33 million extension they signed Sanders to earlier this month, the two receivers have plenty of expectations in tow. And while this week's comments are fairly mild given the Broncos are 2-0 with a first-year starter at quarterback, they still reflect some frustration in an offense that has scored four touchdowns in two games.

Sanders and Thomas did have similar starts last season when Peyton Manning was playing on an injured foot and the Broncos were battling injuries in the offensive line. Sanders didn't have a 100-yard game in 2015 until Week 5 and Thomas had one 100-yard game in the first five weeks of the season, too. Siemian will make his third regular-season start Sunday in Cincinnati.

"Those plays will come, those guys are going to make those plays," Siemian said.

"It's his second start, it's going to take time," Thomas said. "I don't know ... why the ball is not coming my way, but it's not a big deal, at the end of the day it's all about winning, we're 2-0 right now."
