I don't think it has anything to do with being classy. I think a few people would look cool with dark visors.
I've always wondered that myself too. There are some teams where it seems like half the team wears visors, but for some reason nobody wears one on LSU that I know of.
I would sure wear one if Moe played on the other team. I would hate to get poked in the eyes the way he does to Curley.
Tiger Stadium, even after the new light stanchions on the East Upper, is notoriously poorly lit compared to other night time game oriented stadiums. Throughout the mid 90's of the DiNardo era, and on up into the early years of the Saban Era for all the night games, they routinely roped off a section outside of the South End Zone to make room for temporary light stanchions to aid and assist the television audience to obtain better lighting. I'm sure that affects player's vision as well as it does the cameras...
I've always wondered why some defensive lineman doesn't put a small amount of vaseline on one sock. Then, when the guy with the visor is at the bottom of the pile, you smear a little on it and he has to go out for a few plays to change the visor.
spit or mud would work I guess. Actually I dont know how anyone wears a visor and plays but then I dont like players wearing gloves. Both seem to more of a detriment than help. Doesnt seem you could get the feel for the ball with gloves nor see as well with a visor...much less a tinted one.
