Why does it always come down to the discussion of BPA vs Need? Why cant it be both?

Why can't it be picking BPA at a position of need?

If your stuck with pick 19 and have holes in more then 3-4 areas that you could not fill with FA then its dangerous to pick BPA. This is what has gotten us in trouble over the last couple of years leaving us with huge holes coming into the season.

First it was Ireland completely negecting the CB's one season then completely neglecting the OL this last season.... BPA at a position of need wil gaurantee your filling holes.
