Provided an opening after practice Thursday to display his self-deprecating humor, Jaguars defensive coordinator Todd Wash delivered when ask how difficult the transition will be for new nose tackle Marcell Dareus. “I’ve coached D-Line [since 2008]; if it was hard, they wouldn’t let me coach it,” Wash said. Funny guy. But to hear everybody tell it, indoctrinating Dareus – acquired from Buffalo for a sixth-round pick on Oct. 27 – has been seamless. He is expected to make his Jaguars debut Sunday against Cincinnati, joining a defense that is first in scoring but last stopping the run. The Dareus trade was fascinating for two reasons. The Jaguars knew their defensive line was a strength and they added to that strength instead of addressing other positions. The Jaguars have many key off-season financial decisions and they added Dareus’ contract, which has a $10.175 million salary cap charge in 2018. Did they absolutely, positively need Dareus to make a run at the AFC South title? Probably not. But he could make the Jaguars the division favorites if he is engaged.
