Before the season started, defensive tackle Sen'Derrick Marks signed a one-year, $1.5 million contract with the Jaguars so he could prove that he was worth a multi-year deal worth millions of a dollars.

After a 2013 campaign in which he's recorded four sacks and batted down eight passes, Marks reportedly has earned exactly that, agreeing to a four-year deal worth up to $22 million, according to NFL.com.

To compare, Marks spent the first four seasons of his career with the Titans. His combined statistics from 2009-12: eight broken-up passes, three sacks. This season, then, was a pretty good turnaround (according to measurements by Pro Football Focus, which ranks him as the 29th-best defensive tackle in the league, Marks also has accumulated 11 quarterback hits and 24 quarterback hurries this season).

"Not many three-technique guys can do the things [Marks] does," Jacksonville linebacker Paul Posluszny said last week, via the Florida Times Union. "He's very athletic, moves really well. He has that great combination in a three-technique where he can hold up against the run and rush the passer.

"He should get what he deserves [financially]. He's playing at a very high level right now. We want him here. We want him to be a piece of our defense in the future."
