Anyway, back to my point, the statnerds dig a lot deeper than we do. From your top 25, I've seen the majority of 3+ games from your top 9. I feel I have a valid opinion of them. I've seen virtually nothing but highlights(and a game against OSU) from 10-11. I wouldn't venture to compare them to the top 9. 12-19 with the exception of UCLA, 3+ again. NIU-0, UCF-2, OK-2, LOU-1.5, Miss/Wash-0.
Now, how in the hell could I have a valid opinion on a team that I haven't really seen play at least twice? So, like you, I'd look at stats. Which is EXACTLY what the S&P+ people do. Except, rather than using final score and total yards, they dig a LOT deeper than that. That's why their process has MERIT. Whereas your process is virtually meaningless by comparison.
IOW, when we start discussing the WCW champ, you'll be a fine source. CFB, not so much.
