Summary

Fielding Yost,  Football for Player and Spectator… (1905)

“ The famous "whoa back" play is a portion of the offense and a general shifting formation in the various plays is always in evidence.
No particular form of defense characterizes Chicago, judged from a basis of the method of play of its various elevens, but the defense generally includes a combination of three men back of the line, shifting to two as the style of attack of the opponents shows to be necessary. Chicago's teams have also been famous almost every year for the possession of some member with remarkable ability at punting and securing goals from the field.

Fielding Yost,  Football for Player and Spectator… (1905)

“ There is more so-called open play in the west, less of compact formations and of the slow pull-together game. Another characteristic of the western game, as distinguished from the eastern, consists of faster consecutive execution of the plays. Therefore much interest is evidenced in the south when teams representing the eastern and western systems meet in contest. It was thought by many that football would not be popular in the south, the warmth of the climate being assigned as the cause. ”
