I think everyone just needs to accept that the F.O. know more than any of us do. They made the right pick because even if you believe that Tunsil was the better prospect it is a very slim margin so Stanley wins out due to him being a cleaner prospect.
Also it is not just convenient that people started liking Stanley better right before the draft, it's due to the fact that as we get closer to the drafts the media actually starts catching up to what NFL FO's are really thinking.
Without them having played a single down yet Stanley was the right pick because they were both very close talent wise. In three years when we can actually evaluate their play we can make a decision on whether or not Tunsil was worth the character and injury concerns.
