The Broncos have offered Ryan Clady a five-year, $50 million contract extension with $28 million guaranteed, according to a source. The $10 million a year average would make Clady one of the league's five highest-paid offensive tackles. He is scheduled to make $3.5 million this year. However, the source said Clady and his agent, Pat Dye, are seeking a deal that would slightly exceed the contract of Browns left tackle Joe Thomas, who received an extension last summer that averages $11.5 million a year.
