I played in a few college games when I was in high school. My brother in law played at Texas A&M back in the mid 70s. There were not enough players to make a team, so it was worked out so I was able to play.
I was a high school football player and not used to the rules of rugby. I wanted to take out the guy with the ball. So the ball carrier tosses the ball to another player and I would still take the first guy out. I guess that is against the rules. But most of the opposing players started getting rid of the ball when I was 10 feet away. Plus I still hit everyone like I did in football.
Mind you I was 16 years old, still in high school and playing college rugby, and I am the one thrown out for being too rough. I never thought of rugby as a rough game since.
Oh well, even football isn't what it used to be.
