I think we're talking about two different things and I respect your experience, though I think you shouldn't be shocked, shocked, when I don't know about "data that is out there" for college football, which I don't follow. After all, I'm not a football player, just your average message board poster who presumably would ace the wonderlic.
Speaking of which, would you really want to pit average message board members (Tom Casale was one of them) against football players? How do you think he'd score? That's really what I meant about lacking empirical evidence.
Anyway, I wasn't talking about college football and neither was the article (remember the article? thread's about the article). I was talking about the NFL, which narrowly selects from college football, just as academic colleges narrowly select from high schools. I certainly wouldn't justify a statement about college students by citing statistics on high school dropouts.
We've gone a bit far afield, so I'll leave it at that. Remember to smile, we're having fun here.
I'm using college football as the measure because that's where one can draw empirical evidence that measures the average football player against the average college student. And the NFL doesn't select narrowly based on intelligence but rather on other factors. In fact, the higher up you go into the athletic skill rankings for colleges, the more the deficient they are in terms of their literacy scores. Why? Because colleges are much more likely to try to make "arrangements" for superior athletes than they would for average athletes. So, the narrow selection actually works against the NFL athlete (in terms of literacy) since the top college football players are also disproportionately "less literate" than the average college football player. This assumes, of course, that by top I'm referring to the kids with many offers from the well-known football factories, the kids who, by and large, end up landing in the NFL draft eventually.
As for Tom Casale, let me put it to you this way: Can he read at an adult level? Then yes, he probably surpasses a majority of players. I don't want to impugn all players since a lot of them take real majors. But the numbers don't lie. When a majority of a school's football players achieve substandard scores, enroll in bogus classes, don't graduate, and enroll in the same major (in some cases reserved for football players) then it doesn't take a brainiac to know what's up.
The vast majority of NFL players come from college, and that's why I brought up those collegiate measures. That's why I referred you to college data as one of the empirical measures of intelligence.
Other than the wonderlic, I can't think of any other empirical measures.
Seriously, take a look at the wonderlic:

I submit to you that NOT acing this test means you are not capable of making adult and responsible decisions in our society today. It doesn't mean you can't be a football coach, however. You can. If by football coach we mean offering insight into aspects of your position and/or offering encouragement and advice to people you're training. I have doubts that you could have questionable literacy skills and have any strategic responsibilities in terms of coaching. Most of those guys are capable of abstract thinking and, yes, manipulating a computer. But then again, look at Wade Phillips.
I'll give you one more example of how this breaks down: when I worked the court/jail system as a younger man, I would marvel at how felons in the system could calculate instantly how much actual time they would have to do. If they agreed to a plea of 250 days, they would know instantaneously that this meant only 83 days to serve (or whatever). In their world, that's all they needed to know. Just because they had that skill set and form of intelligence does not mean they could move on and learn to master other things. Most of these men were either illiterate or functionally illiterate. The implication I'm drawing is that we all have a certain level of intelligence but that building the skills (in today's world, these are mostly literacy skills) to prosper takes a lot of work, and if you haven't done it at a younger age, it's going to be difficult to catch up. Judging by college football recruitment, most top football players have not built up sufficient literacy and life skills to survive outside the sport.
Just look at that wonderlic.
