Broncos free agency: Defensive tackle Vince Wilfork could help Denver's defensive line

In Denver's 3-4 defense, Derek Wolfe and Malik Jackson are ideal defensive ends. But what about defensive tackle?

Terrance Knigthon would have been a good fit, but he is not expected to return.

Vince Wilfork, who will become a free agent on Tuesday, may be an option.

"I want was informed on Tuesday that the Patriots will not be picking up my option," Wilfork tweeted on Thursday. Wilfork, 33, had a base salary of $3 million in 2015, but a March 10 roster bonus would have made him a $8.9 million cap hit. He will now become a free agent.

Weighing in at 325 pounds, Wilfork's main duty in New England was to eat up blocks. He played in 73.4 percent of the Patriots' defensive snaps last season, according to ESPN's Mike Reiss.

New England selected Wilfork 21st overall in the 2004 NFL draft. He went on to win a pair of Super Bowls with the team (XXXIX, XLIX), earning five Pro Bowl selections along the way. Over the past eleven seasons, he has recorded 516 tackles, 16 sacks, and knocked down 25 passes.

If Knighton does not return, Denver will be in need of a big run-stuffer to anchor their defensive line. Entering free agency, Sylvester Williams (313 pounds) and Marvin Austin (312 pounds) are the only two defensive tackles the team has under contract.

If the price is right, Denver should consider Wilfork.
