Coach Shaughnessy never had such a wealth of material as 1925. The backfield included captain and Hall of Fame quarterback Lester Lautenschlaeger and halfback Peggy Flournoy. Though he was famous for later using the T formation, at Tulane coach Shaughnessy employed the single wing. Assistant Bierman left for the Mississippi A&M job. 1925 saw the south's widespread use of the forward pass.
The season opened on a wet, sloppy field. Tulane beat Louisiana College of Pineville 77–0. Coach Shaughnessy only allowed his regulars to play half of the game. Lester Lautenschlaeger was probably the star of the game.
Missouri
The only blemish on the year was a 6–6 tie to Missouri. Missouri scored on a 30-yard pass. Peggy Flournoy plunged over for the tying touchdown. The starting lineup was Gamble, Wight, Levy, H. Wilson, Blackledge, Talbot, Brown, Lautenschlaeger, Morgan, Flournoy, Norman.
Mississippi
The Green Wave used the forward pass to beat coach Homer Hazel's Ole Miss Rebels 26–7. The starting lineup was Gamble, Wight, Levy, H. Wilson, Blackledge, Talbot, G. Wilson, Lautenschlaeger, Morgan, Flournoy, Lamprecht.
Mississippi A&M
Former assistant Bernie Bierman's Mississippi Aggies took the lead 3–0 in the opening quarter with a drop kick. Harry P. Gamble blocked a couple of kicks and Tulane came back to win 25–3. After the defeat of the Aggies, some Tulane supporters felt the Wave would defeat Alabama. The starting lineup was Gamble, Wight, Levy, H. Wilson, Blackledge, P. Brown, D. Wilson, Lautenschlaeger, Flournoy, Morgan, Lamprecht.
Northwestern
In the 18–7 triumph over Northwestern, Flournoy scored three touchdowns and skied his punts. Northwestern's score came in the second period. The starting lineup was Gamble, Wight, Levy, H. Wilson, Blackledge, Talbot, Wilson, Lautenschlaeger, Flournoy, Morgan, Lamprecht.
Auburn
On a field thick with muddy, Alabama clay in Montgomery, the Green Wave won over the Auburn Tigers 13–0, scoring all points in the second half.
Louisiana Tech
Flournoy scored 31 of Tulane's 37 points in the win over Louisiana Polytechnic despite Tulane using mostly reserves. The starting lineup was Gamble, Browne, Levy, H. Wilson, Blackledge, Wight, D. Wilson, Lautenschlaeger, Menville, Flournoy, Lamprecht.
Sewanee
Tulane defeated the Sewanee Tigers 14–0. All scores took place in the third quarter. A 32-yard pass from Lautenschlaeger to Brown set up the first score. On the second, Flournoy got loose for a 68-yard run off tackle.
LSU
After a scoreless first half, Tulane beat the rival LSU Tigers by a 16–0 score. A pass from Lautenschlaeger to Menville got the first touchdown. The final points were scored by Irish Levy dropping the LSU quarterback for a safety.
Something of an anticlimax after the LSU game, Tulane beat Centenary 14–0 to cap an undefeated season.
Postseason
Tulane shared the SoCon title with Wallace Wade's Alabama Crimson Tide, which went on to win the Rose Bowl. Tulane's administration declined a Rose Bowl invitation, in order to keep their student-athletes in class. One account reads "In the South they call "Peggy" Flournoy of Tulane University, the greatest all-round gridder in that section." Flournoy led the nation in scoring in scoring with 128 points, and was awarded the Most Valuable Player award by the Veteran Athletic's Association. He was selected by Billy Evans and Norman E. Brown as a first-team halfback on their 1925 College Football All-America Teams. He was also named a second-team All-American by the Associated Press and the All-America Board. Flournoy and Irish Levy were All-Southern. Levy was never taken out of a game for an injury during his playing career. Lautenschlaeger made Billy Evans' Southern Honor Roll. Flournoy's school record of 128 points was not broken until 2007 by Matt Forte.
