You can laugh if you want, but the truth is he was a solid coverage linebacker last year. Now, he can't blitz very well and he's on skates against the run and takes bad angles, but if you need someone to shadow a tight end or running back, he showed he could do that.
I want more from my nickel linebacker than that, but right now, we don't know if we have a backup who can handle the coverage part of that role. That's why we might have to keep Brooking on the field on third downs against the Commanders and at least for a few weeks of the season.
I expect Lee to eventually take the role, IF they'll let him focus on it in practice.
