I agree with defense with the 1st pick especially with the way this particular draft is setting up, Thiibodeaux or Hamilton to be specific, but this seems like a good draft to get a potential QB steal in the late 1st if Willis or Corral drop to the Rams pick then you can take WR with the 2nd depending on how the board looks at the time. QBs with huge upside but also raw enough that they could slip into the 20s. Not to mention that there aren't many teams with QB needs after so many were taken last draft.
I know that a lot of you don't like the idea of taking a QB high in the draft this season but the Lions are actually in a pretty good spot to take a flier on one now with their building strength on the offensive line and a good bridge QB in Goff to allow them to redshirt the rookie QB so if you have a chance to nab a potential franchise QB with the late 1st, you'd have a potential foundational piece on offense and defense in the 1st round alone with many more picks to build elsewhere. QB is THE most important position, better to jump on one sooner or later if you fall in love with the potential of one. This is the luxury that having that extra 1st affords them.
