Brandon Krisztal of the Denver Post reports that a source close to Broncos DT Terrance Knighton has informed him that Knighton and his representatives believe he has outperformed his contract and are looking for a new deal.

Knighton, 27, signed a two-year contract worth $4.5 million and will make $1.5 million for the 2014 season. He came up big for the Broncos in the AFC Championship game against the Patriots totaling four tackles, two of which came for a loss, and a crucial sack that had a big impact on field position.

Pro Football Focus has him rated as the No. 9 defensive tackle in the league this past season and graded out almost as good as an interior pass rusher as he did in run defense, which is really something for a guy of his size.

I’m sure the Broncos would be willing to discuss an extension if their cap situation was better than it currently is. As things stand right now, Denver is projected to have over $12 million in cap space, but they also have a number of key free agents to address as well as some important extension candidates to take care of as well, so we’ll have to if they even engage in long-term talks with Knighton this offseason.
