There likely will be at least two returning starters on the Denver Broncos' offensive line.

Although the team hopes to procure a pair of linemen in free agency, they feel they're "set" with incumbent Max Garcia at left guard, 9 News' Mike Klis reports.

Denver will make a run at the top interior protectors on the open market. Cincinnati's Kevin Zeitler is considered the cream of the crop, but his price tag ($11 million annually) is probably "too rich" for the Broncos' blood. They've also been linked to Dallas' Ronald Leary and Green Bay's T.J. Lang, who's seeking a more manageable $9 million per year.

Either of these players would represent a massive upgrade on Michael Schofield, who graded out as Pro Football Focus' No. 50 OG out of 72 qualifiers, drawing especially poor marks for his run-blocking.

Denver currently boasts $42 million in available salary cap room. They'll have plenty to sign a premier free-agent or two, with enough left over to lock up their own.

Additionally, Klis says, the Broncos aren't looking for a right tackle, suggesting Donald Stephenson may return in 2017. Stephenson, whose disappointing 2016 campaign was well documented, is due $4 million in base salary for next season.

“We want a left tackle,’’ head coach Vance Joseph said at this week's NFL Combine.

The Broncos will pursue Andrew Whitworth, the top available OL on the open market, as a successor to Russell Okung. Which means Baltimore right tackle Ricky Wagner is out of the question.

It's possible, if not probable, that Stephenson returns at a discounted rate, or the team finds his replacement via the draft. They also might consider a few in-house options -- Billy Turner, Ty Sambrailo, and even Schofield -- to take over at right tackle.
