I play on a Friday against a girls team. I am pretty good but I'd say 80% of them are better than me. So the answer is yes.
a big "YES".
I think so because no matter how old you are you should be able to play football if you're a girl because a girl can do anything a boy can do and because football is just simple genetics and if the girl really think there tough then they can handle it and no they shouldn't have all boy teams then all girl teams. They should let boys and girls play on the same teams and not split up and honestly i think football should make girls tougher.
Yes Girls can play football... Just kicking the ball is playing too... Look at the National Female Teams, they play football very nice...
I don't know about only fat people playing football, look at Adrian Peterson aka Mr. 1% Bodyfat. The fattest people you will see playing are the offensive linemen. As far as the question, can girls play football? Im sure they can play, anyone can play for fun, but I doubt they will be any good at it, just being honest!
