So how many for 2 wickets would England need to be at the end of play

[SWv2]

Surely if we get to the end of play with 7 wickets in hand and need less than 200 we'd be favourites?

Not sure as obviously the batting quality is diluted as you go down the order so an average of 30 per batter is quite high given the stakes etc.

Obviously you are greatly aided by one of your better chaps having some *******s and getting an individually high score.

I expect a more experienced Cricket follower would be better placed here.
