That's about on par with other teams though, granted once you have a franchise QB, you're not drafting in a QB in the first anytime soon. Cleveland leads with 1st round QB's taken in the last 20 years and that's only 4. NE, Seattle, and KC have 0 in the past 20.
last 1st round QB pick per team:

about 50/50 for first round QB's to pan out.

I do want the Bills to draft more later round QB's though, it's worth a shot.
