England cricket

I'd backed England to win the series after they lost the first Test as I thought they were the stronger team and the odds were tempting (similar scenario to a nice bet on the Ashes). After the fourth day's play I notice Bet365 have England 7-2 to win the Second Test but still 14-1 for the series. If they do win this Test England will surely be no bigger than about 6/4 for the last Test, which would win them the series, so the 14-1 looks huge.
