Not the best, perhaps not even great, just good enough not to have to pander to this silly 'England is crap at all sports' nonsense.
Rugby. Yes, beaten fair and square, but still won when it counted. Clearly one of the top three teams in the World.
Footy. Premier league acknowledged for excellence, national side in last eight in Europe, and probably capable of top four. Beat Germany 5:1 in recent memory. 5:1. And while Greece were the outsiders they beat France and Portugal. While our defeats by those teams were unlucky, at best.
Tennis. Henman is top ten in the World, as shown on clay in Paris and at Wimbers.
F1: Ferrari's success is largely down to Russ Prawn (a Brit). Most of the top teams are Brit based or rely on Brit engineering.
And there are a host of other sports where England excels, or where there are English participants at the top or near the top of the tree. Boxing. Marathon and distance running. Triple Jump. Javelin. Rowing. Sailing. Gliding. etc.
