Personally I view Grace and Ranji as belonging to two different eras - Grace's FC career may have extended through most of Ranji's career but after 1895 Grace wasn't what he used to be.
In fact, Grace's FC career started 7 years before Ranji was born.
I don't disagree that Grace and Ranji were from different eras, but to claim Grace wasn't what he used to be "after 1895" is a very poor choice of year. Between 1895 and 1898, Grace went through a late renaissance and was in the best form he had been for around a decade. Just take a look at his stats in these seasons as opposed to the seasons directly preceding 1895:
Grace made 30 first-class appearances in 1890, scoring 1,476 runs, with a highest score of 109 not out, at an average of 28.38 with 1 century and 9 half-centuries.
Grace made 24 first-class appearances in 1891, scoring 771 runs, with a highest score of 72 not out, at an average of 19.76 with 0 centuries and 5 half-centuries.
Grace made 21 first-class appearances in 1892, scoring 1,055 runs, with a highest score of 99, at an average of 31.02 with 0 centuries and 8 half-centuries.
Grace made 28 first-class appearances in 1893, scoring 1,609 runs, with a highest score of 128, at an average of 35.75 with 1 century and 11 half-centuries.
Grace made 27 first-class appearances in 1894, scoring 1,293 runs, with a highest score of 196, at an average of 29.38 with 3 centuries and 5 half-centuries.
Grace made 29 first-class appearances in 1895, scoring 2,346 runs, with a highest score of 288, at an average of 51.00 with 9 centuries and 5 half-centuries.
Grace made 30 first-class appearances in 1896, scoring 2,135 runs, with a highest score of 301, at an average of 42.70 with 4 centuries and 11 half-centuries.
Grace made 25 first-class appearances in 1897, scoring 1,532 runs, with a highest score of 131, at an average of 39.28 with 4 centuries and 7 half-centuries.
Grace made 26 first-class appearances in 1898, scoring 1,513 runs, with a highest score of 168, at an average of 42.02 with 3 centuries and 8 half-centuries.
A more accurate statement would have been "after 1898 Grace wasn't what he used to be".
