Rublev’s default from Dubai generated tons of discourse this week, and we devote quite a bit of time to it: the facts, the question of proportionality (of both Rublev’s actions and the umpire’s decision), and why player reactions aren’t the final word. We also recap the end of the lead-up to Indian Wells, with several players showing off the best tennis of their lives. Plus, Murray’s retirement talk; the ATP’s partnership with Saudi Arabia’s Public Investment Fund; and the suspension of a low-ranked player for cannabis and how WADA decides to ban a substance.
