Thanks to all these runs from Smith and Kohli, plus more runs from other captains, 2017 was an outstanding year in terms of runs from captains, both in Tests and in ODIs. In Tests, there were seven captains who scored 500-plus runs at 50-plus averages; apart from Smith and Kohli, the others who managed this were Kane Williamson (average 62.88), Mushfiqur Rahim (54.71), Faf du Plessis (54.30), Joe Root (50.84) and Dinesh Chandimal (50.40). All of those runs made 2017 only the second year since 1980 when the overall average for Test captains was more than 50. In ODIs too, their collective average was second-best since 1980, thanks largely to Kohli (1460 runs at 76.84).
