I know nothing about rugby nor do I care, but to decide who I think will win, I'm going to use a random number generator and set it to pick a randomly between 1, 2, 3, 4, 5 and 6. England is 1. Scotland is 2. Wales is 3. Ireland is 4. France is 5. Italy is 6.
The random number generate chose 6, so therefore I predict that Italy will win the 6 nations.
Cricket is mind numbingly terrible so I'm going to ignore it.
But England do reasonably well in Rugby and in (Real) Football, England doesn't have one sport that the specialise in and can't do anything else; like Wales and NZ. They do very well at lots of different things.
And the US are useless at every sport that other countries care about.
Wales will win, but Ireland could be a surprise, they did very well in the Autumn tests
