This is the problem. Every year is different and unique. There are 4 players head and shoulders above the rest(Embiid,Wiggins,Parker,Exum). So to answer your question, that's why you want a top3 pick. These GM's are not dumb, look how they held onto the 1st round picks like gold at the trade deadline. This is a unique year, with game changing, franchise players in the top 4. All those stats above about being in the top 3 don't hold water in my opinion.
