Jonah Lomu was a freak combination of size and speed. He weighed about 260 lbs and could run the 100 in less than 10.0 seconds. Rugby players are a fearless group but in the 1995 WC the English players were reluctant/afraid to tackle Lomu. Yet South Africa upset the All Blacks to win the WC. If you have ever played a S. African team, they have legs the size of telephone poles and are ruthlessly physical.
Unfortunately, Jonah's career was brief. He died of kidney disease at age 40 about 10 years ago
You can watch the best professional leagues on Flosports, an inexpensive App that includes about 25 international and domestic sports. They have the :
1.URC-Ireland, Wales, Scotland, Italy and South Africa professional teams
2.Super Rugby-New Zealand, Australia, Pacific Islanders and Argentina
3.English Premiership
4.Top 14-French teams
I would suggest watching Leinster (Dublin) from the URC, Canterbury or Auckland from Super Rugby, Toulouse, La Rochelle from the Top 14 and avoid the English Premiership because they play a boring style of rugby.
I will typically watch about 10 or more games per week, never missing Leinster because of their backline play
