Not necessarily. “Drops” unless egregious, are partially subjective. Who measured the data?
A “drop” can be a ball going through a WR hands on a bubble screen. Well, was the pass too high? Was it too low? Was it rifled when it should have been feathered? Just because it was a “drop” doesn’t mean the QB threw a good pass.
It all depends on if there’s a strict criteria.
I get the point you’re presenting and on the surface it makes sense, I just think “adjusting for drops” is lazy.
