....these sorts of things.
LIke what you wrote overall; think that IQ tests misrepresent a lot---and don't measure spatial IQ, and creativity and all sorts of other things that could matter in the NFL;
however, O lineman, WRs and QBs probably need to be well-versed in what "society" deems "education" because the NFL's system in based in the world's system--which IQ tests
partially measure.. Safeties, MLBs and TEs could be added to the 'need' intelligence list, too.
Most guys who are "smart" get pretty good scores; guys like Marino and Peyton Manning are for sure not 'so smart', and it didn't matter because of skill, and for the latter work ethic
made him look smart (yes, I am not so smart myself, that is why I recognize Marino and Manning as avg.).
It is very evident that the O lineman that the Rams drafted last year and this year, have good intelligence; add the safety, too. I think 3 of those lineman have a decent level of physical talent, but it is evident to me that there were many other lineman the Rams didn't draft and I think IQ tests is part of that reason. Evans the G/T was known as a good 'communicator'---which is huge, too---and may be a sign of intelligence or confidence, or just loving to be 'sure' about what will happen on the field; either way Evans is all good!
RBs probably have the least nned for huge intelligence- notice RBs like A Petereson who are/were taken off the field on passing downs. AP, after 10 years, still can't stay on the field on passing downs---this probably indicates he is 'lower' than the other RBs in intelligence (can't set up a screen, and hands, maybe, too)....probably.. IQ tests do reveal something, but certainly not everything. Look at how Bradford was 'lost', despite being highly intelligent and a geat athlete in gen. Heath Shuler, old QB, had a low score, and the press reported that 'in shorts' no one could throw like him, but once the action came, he couldn't handle it. NOtice the passing down RBs are always smarter--whether it is Amp Lee or Ronnie Harmon or Faulk....they are always more intellgient.
Intelligence in the NFL matters, and the NFL uses a test to find the smart guys, and elevate them, while at the same time, in a bad way, guys like Tavon and Greg Robinson get many times get a 'pass' on this important trait. Their inability to 'handle' a system cost the Rams seriously. I am not surprised about Tavon, but I am about Robinson---if I remember he had a decent score (high teens, or up to 23 or something).
I find myself being TOTALLY deficient in understanding systems--I am very, very slow to recognize certain patterns; and so, maybe I am like Greg Robinson in my own way. Thank you Jesus that there are other things that I can do with talents He gives.
