Last year, I remember seing some teams make the framework argument that every case should have a "solvency advocate," or someone/piece of evidence that specifically and more-or-less explicitly says "We should do this plan." However, I've only ever seen this argument made as an analytics argument, a throwaway make-the-2AC-respond-then-promptly-drop-argument.
So, my question is, is this argument ever made in a serious (round-winning) context? And, if so, what evidence and standards could teams use?
