When did the holding penalty go from 15 to 10 yards?

Answer 1

The holding penalty in American football was reduced from 15 to 10 yards in 1978 as part of a series of rule changes aimed at increasing offensive production. This change was implemented to discourage defenders from committing holding fouls that could significantly impact the outcome of a play. The adjustment was made to create a fairer balance between offense and defense and to promote a more dynamic and high-scoring style of play in the NFL.

Answer 2

Before the 1974 season, the NFL changed the penalties for offensive holding, illegal use of the hands, and tripping from 15 yards to 10 yards.
