If the defensive man will move with the offensive man, then the offense should be able to isolate one man and the point of attack should be directed toward him. [Figures 101a-b] illustrate the center’s man and the offensive right tackle’s man being isolated respectively, and the critical point of attack being directed at the isolated defenders.

It is very important for the offensive lineman to know his main objective in proper line splitting is either (1) to spread the defense out, or (2) to isolate a man. The main objective is never to split in order to get a good blocking angle. This latter misconception can destroy any advantage we gain by splitting the line.
