NFL - American Football is more competitive and aggressive than soccer.
general rules are
each team holding the ball, have 4 chance to move the ball on their offense side - at least 10 yards.
after 10 yards, they have another 4 chance till touch down
there is only one pass of each chance, and only pass forward.
each touch down is 6 points , plus, team may choose to make a 1 points free kick or 2 points game.
and ...each team may choose to use their one of offense chance to kick a free goal if succeeded in doing that, it is 3 points without extra points
and penalty based on play like offline, face-mask, illegal formation, etc etc, each penalty have different numbers like back to 5-15 yards...
so this is general rules, not like ruby, they have multi pass, the key points is ...
NFL has only one pass forward.😀😀
