Maybe different reactions to this are greatly affected by what you assume the Bills will do in the early rounds. I'm assuming 1T/DL in round 1, then maybe CB. That didn't change at all with this signing. So.im fine with this as White being good depth or a stopgap starter.
Imo, our main issue is stopping the run. Hence the DL. I would also like us to play tighter man coverage, but I don't think that'll ever happen with McDermott.
