Simply put, if you draft inferior players you have an inferior team. If you continually draft a player even 0.1 less than available, over the course of a few years your overall team quality will be 6.2 instead of 6.3. If that doesn't seem like much it, it is. The league is so competitive, a 1.7% talent deficit is the difference between 8-8 and 10-6 and in the playoffs.BPAAPON
Best player available at a position(s) of need. Teams will almost always draft a player at a position of need, but they typically have more than one position of need. Also just depends on what that position looks like later in the draft, according to their rankings, and next year.
For example, at the top, the edge position this year is just average. Some quality depth, Chubb, and some decent starters. Next years draft, as of now, looks to be really good at the edge. I can't say for certain, but I would think that plays a role in some teams mindset.
Fans and some GMs on the hot seat only think about the next season and not the entire length of a draft picks career. Needs come and go due to injuries, retirements, etc. BPAAPON, AKA drafting for need, doesn't work.
