Repealing the birth-year mandate and other obvious moves
Some of the initiatives U.S. Soccer has rolled out over the last 10 years are well-researched and sensible.
Restrictions on heading the ball are simply a safety issue, and coaches should be able to adapt to teach proper technique and judging the flight of the ball. (Or, just as a wild notion, maybe playing the ball out of the back instead of blasting it 70 yards up the field and yelling “win it!” to a tall person.) Small-sided games are globally accepted as a better idea than tossing a bunch of first-graders into an 11v11 game.
