PHOENIX -- Snacks Harrison enjoyed a monster first season in Detroit. And now he’s looking to cash in.

The veteran defensive tackle switched agents this offseason and has already approached the Lions about signing a new deal according to a source. It’s unclear how receptive the Lions were to the idea. Harrison, 30, still has two years remaining on his current deal, making a $6.75 million base salary in 2019 and then $9 million in 2020. He also has workout bonuses of $250,000 for both seasons.

Harrison was acquired in a midseason trade last year. The Lions gave up just a fifth-round pick for him, then watched him rack up 30 run stops, which led the team even though he played in just 10 games for them. He added 3.5 sacks and ranked as the third-best defensive tackle in the game according to ProFootballFocus. He was No. 1 against the run, and the Lions’ defense was far better for it.

They ranked 30th against the run before the October trade, then climbed all the way to 10th by season’s end. They allowed just 925 rushing yards after the trade, fourth best in the league, and 3.76 yards per carry. That was second.

Now it seems Harrison wants to be around for the long haul.
