Assuming no team who liked Little wouldn't have traded up ahead of us or no team in between wouldn't have drafted Little is also a hypothetical.
Regardless, whether you agree with them or not, our FO had a first round grade on Little and may have even reached further to draft him at 16 if Burns wasn't there (thankfully that wasn't the case). So in their(FO) eyes, trading #47 and #77 for a top 20 guy is a no-brainer. Again, I am not saying you have to agree with that placed value, but you can see why to them the trade was justified. Of course I would have preferred to get him at 47 while keeping 77 to get another need, but it is hard to argue with their thinking either, knowing they valued Little that highly. They essentially got two guys they considered at #16 and that is a win.
