Damon Harrison transformed the Lions defense after the team acquired him from the Giants midway through last season, most notably against the run.
Prior to the trade, the Lions were allowing the third most rushing yards in the NFL. They finished the season allowing the 10th least.
Harrison, 30, is currently signed through 2020 at an average cost of $9.25 million per year. He has a cap hit of $7 million this season and $9.25 million the one after.
An extension may well be in the cards for Harrison, but it's not on Lions GM Bob Quinn's agenda at the moment.
It probably behooves the Lions to keep him around beyond 2020, but Quinn has time to make that decision.
“It’s something that I got to talk to (his agent Drew Rosenhaus) this week, and going into the future," he said. "Not something that I need to do right now."
