Yes, I play football at the Pro level and there are many skilled position players as well as special teams players that only wear shoulder pads and helmets.. In practice we sometimes only wear shoulder pads and helmets we call it pro-pads we also wear this during training camp a lot and when we are not going to hit full speed.
Soccer players should not wear helmets because they are not an authorized part of a player's equipment under Law 4 of the IFAB's Laws of the Game, the rules the world plays by. This is because in soccer, actions which might cause head injury are disallowed, unlike in American (Gridiron) football, where players would be at a substantial and imminent risk without their helmet.
You need the football helmet mainly for protection ,especially concussions. Way back in the good ol' days, players wore helmets made from leather and without face mask , nowadays players have something to hold on to, of course illegally. The football helmet is also used for the uniform and team identification. The rough and tumble British sport "Rugby",players wear no protection gear at all.
Because they have a death wish. Always wear a helmet. ALWAYS.
