My take is that I'd rather have a guy who's picking FSU BECAUSE of mats and how much quicker and mentally stronger they'll make him over the kid who would rather not come here because of them.
I know the smell you're talking about, RO. Not pleasant. I was responsible for some of that smell a few times. Ugh.
And yes, many other schools do versions of mat drills. Miami University (in Ohio) was visiting us to study them and take them back to their program the week before DD died. Many schools visited us during those days to see what we were doing. Mats actually originated with Bear Bryant, I believe.
