Because real American football involves potentially dangerous physical contact, primary-grade schoolkids across the country often play ''flag football'' (where pulling a flag off of the opponent represents a tackle) and ''touch football'' (where touching the opponent with both hands represents a tackle). Both of these variants usually omit the offensive and defensive lines, and impose a time limit - often 3 seconds - before linebackers can rush the QB. | Because real American football involves potentially dangerous physical contact, primary-grade schoolkids across the country often play ''flag football'' (where pulling a flag off of the opponent represents a tackle) and ''touch football'' (where touching the opponent with both hands represents a tackle).
