I have young sons wrestling folk style now, and that has peaked my interest in free style. I've noticed the radical difference in the match set up and scoring between the matches I've watched from the middle/late '80s and today. Why the switch from the two three minute periods plus over time to the best two out of three periods with that goofy ball draw if there's a tie. That just seems to encourage hanging around for the tie and hoping for the best. Have there been other big rules/set up changes between those time frames too?

Thanks for the education.
