You have to respect title IX, there is no way around it. When I played high school soccer in Illinois a couple of the top 10 teams in state had girls that played on them. I didn't see any preference from the refs when it came to making calls. Most got shoulder tackled off of the ball just like the guys. I know coaches get mad when you play differently against the girls. I had a coach that would bench you if you didn't play to your full potential and knock girls off of the ball if you were playing against them. Its part of the game, as long as it isn't intentionally rough. I have seen some girls that are way better than guys. My wife was an all state player back in the day, and we have played in some 3 v 3 tourneys and she has torn some guys up. I give them props for being out on the field. My brothers gf also played on a guys U18 team as a keeper in NC, and pounded some guys when they came in to shoot. Its cool to see girls that are that good, and want to play with the guys!
