Toronto fans piled onto Sergei Bobrovsky after the veteran stepped onto the ice during Gavin McKenna's solo rookie lap before the No. 1 pick's NHL debut against Montreal.
Bobrovsky's pregame superstition drove the clash: the new Leafs goalie insists on being first onto the ice, so he emerged early and waited near the benches while McKenna circled alone.
McKenna still completed the tradition, but the moment drew outsized scrutiny because the rookie is viewed as a franchise-changing talent in Toronto's intense market.
The backlash also revived an offseason irritation over No. 72, which Bobrovsky kept after joining the Leafs, forcing McKenna to switch to No. 92 because No. 9 is retired.
