The 1903 team went 4–1–1, and opened the season by beating Georgia 29–0.
The next week, Clemson played Georgia's rival Georgia Tech.
To inspire Clemson, Georgia offered a bushel of apples for every point it scored after the 29th.
Rushing for 615 yards, Clemson beat Georgia Tech 73–0.
The team then beat North Carolina A&M, lost to North Carolina, and beat Davidson.

After the end of the season, a postseason game was scheduled with Cumberland, billed as the championship of the South.
Clemson and Cumberland tied 11–11.
While both teams can therefore be listed as champion, Heisman named Cumberland champion.

In 1902 and 1903, several Clemson players made the All-Southern team, an all-star team of players from the South selected by several writers after the season, analogous to All-America teams.
They included ends Vedder Sitton and Hope Sadler, quarterback Johnny Maxwell, and fullback Jock Hanvey.

Fuzzy Woodruff relates Heisman's role in selecting All-Southern teams: "The first selections that had any pretense of being backed by a judicial consideration were made by W. Reynolds Tichenor...The next selections were made by John W. Heisman, who was as good a judge of football men as the country ever produced."
