There have been concerns raised among the Detroit Lions faithful about the lack of pass rush we've seen from Detroit's defense throughout the course of the preseason.

The Lions have generated just one sack in three preseason games, and their pass rush is currently graded 27th by Pro Football Focus.

Adding veteran Eli Harold to the front seven this week is further evidence Lions GM Bob Quinn is continually on the lookout for ways to get more out of the pass rush.

The one big mystery when it comes to Detroit's rush this year is how much scheme will play a part in generating it, and how the pressure and coverage will marry together within head coach Matt Patricia's multiple scheme.

It's really the big unknown to anyone not in the defensive meeting rooms or seeing how it's coming together on the practice field.

Ziggy Ansah is expected to be a big component of Detroit's pass rush. He didn't seem too worried when asked Tuesday about Detroit's ability to rush the passer this season. He's confident the defense will be able to pressure opposing passers when they start scheming to do so.

"Obviously, it's going to be a dynamic scheme," Ansah said after practice Tuesday. "We're going to do any and everything, so just wait until the season and you'll find out. I'm excited about it."

Patricia was the defensive coordinator in New England last year, and the Patriots ranked seventh in the NFL in sacks with 42 and had 15 different players record at least one sack from all three levels of their defense.

Ansah was Detroit's leading pass rusher last season with 12 sacks. He's not likely to play in Thursday's preseason finale vs. Cleveland, which means he should be healthy and ready to go heading into the regular season opener vs. the Jets. Sept. 10th.
