Trey Flowers moving to OLB in Lions new-look base defense

Flowers had his best years playing that role in New England

The defensive line depth in Detroit went from being a weakness to an abundance of talent in the offseason. In fact, the Lions have so many capable defensive linemen now that the best returning player, Trey Flowers, is switching to linebacker.

That’s according to new Lions DL coach Todd Wash, who met with the media on Thursday and provided a deeper glimpse at how Flowers will be used.

Wash acknowledged what head coach Dan Campbell said a couple of weeks ago, that the Lions “will be a 3-4 (front) out of base (scheme).”

He envisions Flowers as “playing the outside linebacker spot”. Wash then noted that when the team flips into sub-packages that the dynamic changes.

“In our sub and dime package, then (Flowers) is going to be playing the defensive end spot.”

Flowers has primarily played as an end in his NFL career, moving between a 5-tech and a 7-tech in the various “multiple” fronts deployed by ex-coach Matt Patricia in both New England and Detroit. In 2020, Flowers played all but 21 of his 307 snaps on defense on the line.

He does have some considerable, and successful, experience playing in a stand-up OLB role. In the “LEO” role in a 3-4 base defense, the position is responsible almost exclusively at attacking the quarterback from a stand-up role outside the defensive end. Flowers played that role in over 50 percent of his snaps in his final two seasons (2017-2018) in New England and scored the highest Pro Football Focus pass rush grades of his career in that role.

The team added veteran Michael Brockers, a more natural 5-technique end who also outweighs Flowers by some 35 pounds, going off their listed weights in 2020. Second-round pick Levi Onwuzurike is also heavier and capably suited to play the DE role in a 3-man front. Onwuzurike can kick inside to rush tackle when Flowers plays DE in the 4-man front and sub packages.

Dan Campbell says the Lions will use a 3-man front on defense

It’s the first indication that the Lions will roll with a base 3-4

One of the bigger questions surrounding the Detroit Lions and new head coach Dan Campbell is what sort of defensive scheme the team will use.

Campbell and new defensive coordinator Aaron Glenn come from the New Orleans Saints, which used a base 4-3 with one of the three LBs as a primary rush end. The Lions holdovers come from Matt Patricia’s “multiple” front, which used three or four base linemen depending on the situation.

In an interview on Tuesday with Sirius XM NFL radio, Campbell let it out that he plans on deploying a base 3-4 defense.

After talking about the appeal of second-round pick Levi Onwuzurike to the team’s scouting department, Campbell said,

“Just our base defense, you know, we’re going to run a 3-4 style defense.”

Campbell continued, noting the versatility of both Onwuzurike and third-round pick Alim McNeill.

“You can see Onwuzurike playing in a 4i or reduced down to a 3-technique and being able to two-gap at times, control defenders, hit the blocks but also take a side and get up the field as a pass rusher.”

It’s the first real concrete declaration of what style of defense the Lions will play under Campbell and a good idea of how Onwuzurike fits within the scheme.
