I had never seen a match until I was in law school. One of my law school friends had played varsity lacrosse at Washington & Lee. He played football and ran track in high school (DC 100 meters champion) and took up lacrosse there. We used to drive to the University of Maryland or Johns Hopkins to watch matches.
From what I saw today, the rules are very different, starting with the faceoffs. They don’t have the 8 meter free shot in mens’ lacrosse to my recollection and a lot more contact is allowed.
This might just be due to the quality of the two teams today, but it seemed that pretty much all of the goals were either scored from the 8 meter plays or individual effort. Not a lot of quick passes to open teammates flashing in front of the goal. Also, no long shots taken; everything was from in close. Again, those could be reflections of the quality of the two teams.
