Although Penn State began competing in intercollegiate football in 1887,[1] the school's official record book considers the "modern era" to have begun in 1970. Records from before this year are often incomplete and inconsistent, and they are generally not included in these lists.
These lists are dominated by more recent players for several reasons:
Since 1970, seasons have increased from 10 games to 11 and then 12 games in length.
The NCAA didn't allow freshmen to play varsity football until 1972 (with the exception of the World War II years), allowing players to have four-year careers.
Bowl games only began counting toward single-season and career statistics in 2002,[2] allowing players in most seasons since then an extra game to accumulate statistics.
Starting in 2018 a redshirted player was allowed to play in up to 4 games in a season and still maintain their status allowing players to gain an extra season of statistics.
Due to COVID-19 issues, the NCAA ruled that the 2020 season would not count against the athletic eligibility of any football player, giving everyone who played in that season the opportunity for five years of eligibility instead of the normal four.[3]
