Hey, you actually did some research for once Rich.
I can see there are a lot of dumbasses like you that don't know the meaning of the word "agnostic."

a person who believes that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena; a person who claims neither faith nor disbelief in God.
skeptic · doubter · questioner · doubting Thomas · challenger · scoffer · cynic · unbeliever · disbeliever · nonbeliever · rationalist · nullifidian

relating to agnostics or agnosticism.
skeptical · doubting · questioning · unsure · cynical · unbelieving · disbelieving · nonbelieving · faithless · irreligious · rationalist · nullifidian
(in a nonreligious context) having a doubtful or noncommittal attitude towards something.
"until now I've been fairly agnostic about electoral reform"
denoting or relating to hardware or software that is compatible with many types of platforms or operating systems.
"many common file formats (JPEG, MP3, etc.) are platform-agnostic"
Here's a picture of that first guy you quoted:
Is that you Rich? lol
If anything a "scheme agnostic" player would not be a player who played in all schemes, but one who played in "no" particular scheme, who was skeptical of all of them. Obviously, not only are you not smart enough to invent the term, you're not smart enough to understand it. But since many of those sources actually use the term correctly, I'll try to explain it to you.
Sports Illustrated: He's talking about the importance of area scouts grading players being "scheme agnostic." They're supposed to discard any notion of a scheme when making their evaluations and simply evaluate the prospect as a football player and let the GMs and scouting directors determine if they fit their particular scheme. Used absolutely correctly.
Inside the Pylon: He's talking about the Oklahoma coach not tying himself to any particular scheme. He's not an Alex Gibbs type coach who runs a particular scheme and favors execution of a small number of plays. Riley doesn't believe in any particular scheme and thus uses them all. Again, used correctly.
PFF: Is talking about using a "position agnostic" approach in evaluating players. They aren't putting any added value to any particular position (even though they admit QB is four times more valuable than any other position). In essence they are valuing each position without believing one position's worth over another. Again, used correctly.
The Ringer: Is talking about Coach Rhule coming to Carolina. Again, saying he doesn't believe in any particular scheme, but he favors a physical approach. Also used correctly.
The Touchdown: Talking about a scheme agnostic "talent" in Okubah. I would have been okay if you said that about Nelson. Talent doesn't have belief.
But you said Quenton Nelson is scheme agnostic. Not true. It's like the Pope walking into a mosque. He might walk in. He might even kneel in prayer. But he's still going to be faithful to his Catholic belief. Nelson might have "scheme agnostic talent," but I will guarantee you that his "belief" lies in a power game. You can see it in his play. His talent might be scheme agnostic, but he himself is not. On the field, he worships these:
He worships them so much, he even tries to get one with his zone "seal" blocks.
Hope you understand, but I'm not crossing my fingers because I don't expect you will or admit it if you do.
