So as I understand it from the article, drafting is a crap shoot so get as many picks as possible to elevate your chances. That's been a mantra I've believed in for a long time. It's an argument I had with one of my brothers, prompting me to research and track all of the Packers drafts back to the 1950s. It's why I also preach that whether your first round pick or your 7th round pick is successful, makes no difference. You get a pool of rookie money each season and a pool of rookies, and the GM's job is to get as many contributors to the team as possible out of each pool.
Maybe they will find a way to make talent evaluation more accurate, but projecting that forward requires so many other variables than just player talent. Analytics in the NFL is another arrow in the quiver, but certainly won't ever revolutionize the drafting process.
