a columnist for the boston globe says it is time to put a ban on heading the ball. he points to growing research that tied the sport to poor cognitive memory, motor skills and changes in brain matter. and one brain trauma researcher quoted in the op ed says what would you do if you saw an older guy hitting a 6-year-old with a fist or baseball bat? call the police. in football, soccer and other contact sports we turn our kids over to coaches and sanction our children to be hit in the head. however, the research is not conclusive and concussions are often not caused by headers, but from collisions with other players. the head coach of mit men s soccer team says the problem with banning heading is you would have kids running out of the way of balls and they may bang into each other to get out of the way. who is right? let s look at highlights from a youth soccer game.
