I stumbled upon this account that collects Bok tries by year and I must say, I didn't expect them to be expansive in pretty much every year until the 00s. I know defences could be well crap in the amateur era, but you kinda expect the big lumps to stick it up the jumper most of the time.

Something I love from the old school era is rolling the ball back for the scrum half to either and pick and run with or dive pass away. I can't remember the last time I saw a dive pass in the modern era.
