I think they have tried, but the Bills scouts are average at best and Beane is proving to be somewhat average at best as well.
They did give Josh a great o-line (recently) as well as Cook, Diggs, Kincaid and other WR’s they thought would be good (but were terrible).
Having said all this, i would have given the kings ransom for Waddle or another stud WR.
In the end, in the large picture, I think we are on the same page - we are failing a once in a lifetime franchise QB.
Time for a new GM and HC.
