A major part of helmitosity is "What have you done lately?", as opposed to how many wins you had before 1968. A team like USC is not going to get as much of a break today in the eye test as will Clemson. If say Washington State suddenly started reeling off 10 win seasons and made the playoffs 3 times in 5 years, they'd get that benefit as well. Clemson is an easy pick to be ranked these days, Number One etc., easy. That is the core of the benefit of helmetosity, how you get ranked preseason and whether it's boosted because you have been there year after year of late, not whatever you did in 1981.
