Tis cricket, you get the bad ones now an then but it cannot be a reason for losing.
Innings scores - Test Series (Red denotes England, Blue denotes India, Italics denote declaration)
474 286 269 261
221 288 544 158
224 710 244
591 300 283
So, save for the first Innings at Trent Bridge, any England innings of the series was better than every India innings of the season, or declared. They took 10 wickets twice, both times at Trent Bridge.
With that record they could never win.
