Two more frequent Princeton running plays are the dive off the strongside tackle and inside traps to the short side, usually with wingback Jim Koloski carrying. The Tigers also will send the fullback over the middle, a play which keeps some of the pressure off the end sweep.

Jelic mentioned that if the defense gets overly aggressive and a man comes through a hole left by a pulling guard, he can be trap blocked completely out of the play, thus leaving a massive hole.

Tail

The most important man in the single wing is the tailback rather than the quarterback, who is used primarily for blocking. The tailback and the fullback both stand about five yards behind the center so that either one many receive the snap from center. The wingback is positioned beside the end on the strong side of the unbalanced line.

Injuries

Princeton's tailbacks along with the injured MacBean are McCullough and Bracken. McCullough, a sophomore, is averaging 5.5 yards a carry to rank second in the league in rushing. He is also first in scoring with 54 points. Bracken has been the Tigers' leader in total offense during the last two years.

The Tigers fullback is junior Ellis Moore, who scored a record 30 points against Harvard last year. Moore is fourth in the league in rushing with 382 yards.

Two Heads

For the last 35 years, Princeton has had only two head coaches, Charley Caldwell and Joe Colman. Colman served under Caldwell and has been at the helm for 12 years now. Under these two men the single wing has always been employed, so that it is not only an effective novelty, but it is a tradition not likely to be changed soon, especially with Princeton's continued success.
