It is indeed a paradox, then, that the rules committee should have simultaneously written a new rule on offensive blocking. This rule, which permits the use of only one arm by the blocker (see illustration below), is strongly slanted in favor of the defensive team. First the coaches open up the offense with their new rule on conversions, then they inhibit it with a new rule on blocking.
Perhaps our sympathies should go out to the referees. They, like everyone else, don't know how to interpret the new blocking legislation. The ones who are meticulous will be blowing their whistles all afternoon long, to the consternation of the spectators. Those who like to see the game proceed apace will simply ignore all but the most flagrant violations.
Football, like everything else in the U.S., seems to thrive on change. If that is a solid premise, then Football 1958 should be a world of fun and very healthy.
