The two major rules changes made by college football's Rules Committee yesterday should have a considerable influence on the Crimson eleven, according to Coach John M. Yovicsin. The NCAA Committee voted to widen the goal posts and ease the substitution rules.

"I am in favor of any rule, not necessarily a two-platoon system, that would allow us to use more players per game and more specialists," Yovicsin stated, calling a more liberal substitution allowance "more important to the Crimson than any other suggested change."

Under the new regulations, any one player may enter the game any time the clock on the field is stopped. The previous rule, which allowed players to re-enter contests twice during the half without penalty, will be continued, but a single player substituted when the clock is dead will not be recorded as an entry.

Yovicsin felt that the next most influential change would be "to put the foot back in football" by widening the goal posts. Next year the posts will be 23 ft., 4 in. apart instead of the 18 ft., 6 in. span in force this year.

The coach also favored moving the goal posts from 10 yards deep in the end zone to the goal line, but this measure was defeated. Yovicsin voted for passage of this proposal at the recent conference of the American College Football Coaches Association in Cincinnati.

Two other changes that Yovicsin had hoped for received little attention from the Rules Committee, as both the two-point conversion and the one-arm blocking regulation remained on the books.
