I have two sons and two daughters, and no my girls may not be as rough as my boys; however, they are just as mean and determined.
1) The parents & coaches tell those kids whether they are big post players or small point gaurds :
TO BE ROUGH DO NOT LET THOSE GIRLS PUSH YOU AROUND.
2) Most of the time the refrees could really care less ( a few care). I have seen a refree call a fall foul for reaching in or coming over the back then see a player tripped or pushed down and just stand there and do nothing at all.
3) I have never seen a boys game be anymore physical, and if you think that you are just plain stupid!
