Ryan Clady has proven to be as tough at the bargaining table as he is on pass rushers.

The somewhat monotonous but extremely serious issue that is Clady's contract negotiations move to the center table this week at Broncos headquarters.

If a multiyear contract extension is not done by July 15, two things happen. One, the Pro Bowl offensive tackle must play the 2013 season on a one-year, $9.823 million salary that came when the Broncos placed the franchise tag on him.

No problem there.

Two, the chances increase that Clady would leave for free agency after the 2013 season.

That would be a problem. Clady isn't just one of the NFL's best left tackles. He's the blindside protector for a brilliant, if immobile, quarterback named Peyton Manning.

Broncos fans have read this before. The haggling between the Broncos and Clady is going on its second year. And the points of conflict have only become more complicated by a depressed players market and Clady's offseason shoulder surgery.

The two sides got serious at about this time last year, when the Broncos offered Clady a five-year, $50 million contract.

But Clady and his agent, Pat Dye Jr., rebuked the offer in large part because of how the deal's first three years were structured.

The $10 million annual average and $16 million in total guarantees were well below the $11.5 million annual average and $23 million in guarantees the Cleveland Browns gave left tackle Joe Thomas in a 2011 contract extension.

Negotiations between the Broncos and Clady broke off before training camp last year. Clady played the season on a $3.5 million salary. To his credit, he played extremely well.
