Although Purdue began competing in intercollegiate football in 1887,[1] the school's official record book considers the "modern era" to have begun in 1946. 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 1946, 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.[3]
Due to COVID-19 disruptions, the NCAA ruled that the 2020 season would not be counted against any football player's athletic eligibility, giving players active in that season five years of eligibility instead of the standard four.
In official NCAA records, "touchdowns responsible for" includes rushing and passing touchdowns, but not receptions or returns—the same statistical categories used to measure total offense.
