Rugby Union. I&#x27;d have to look at the exact numbers, but the New Zealand All Blacks have an amazing win rate. They do play the second best team in the world (either Australia or South Africa) on a regular basis and over the last four years have only lost once or twice. Won the last two World Cups.<p>Edit: Here&#x27;s the data[0]. A 76% win rate since 2003. Twenty-two game winning streak  in 2013. Never ranked lower than 3 in the world since 2003.<p>[0] <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;New_Zealand_national_rugby_union_team" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;New_Zealand_national_rugby_u...</a>
