On the offensive platoon, Caldwell still has most of last year's big line, but he has had to rebuild the backfield completely. Along with Kazmaier, Dick Pivirotto, George Stevens, and Russ McNeil were lost at graduation.

Bob Unger and Bill Tryon have alternated at the tailback position, in Princeton's buck-lateral single wing attack. Although the left-handed Unger is used primarily for passing and the right-handed Tryon for running, they have both proved fairly adept in either department.

Linebacker Homer Smith, a junior, has been switched into fullback post. where he has been an outstanding performer. Smith is fourth in the Ivy League in rushing yardage. Two lettermen, Earl Byrne and Dick Yaffa, both juniors, have exhibited a great deal of speed at wingback. Yaffa, however, may see little action because of an injury.

Senior Bo Willis, at blocking back, rounds out a backfield which the Daily Princetonian calls "one of the fastest Caldwell has ever turned out."

On the line, Caldwell has seven seniors, all of them returning lettermen. McPhee and Len Lyons are at the ends, Bill Ellis and Cowles Herr at the tackles, Jim Otis and Ted Forsyth at the guards, and Red McClain at center.

Caldwell has a good, experienced line, a defensive platoon that has been rather stingy with yardage, and an entirely new backfield that has raised Princeton to the first place in Ivy offense, garnering 196 points
