No. 90 is the new lucky number seven, just ask the most famous emergency backup goalie (EBUG) of all time.[David Ayres](https://www.nhl.com/player/david-ayres-8479188), the only EBUG in[NHL history to earn a win](https://www.nhl.com/news/zamboni-driver-ayres-helps-hurricanes-win-as-ebug/c-315422528)[back on Feb. 22, 2020], had some advice for the newest Maple Leafs goalie pressed into duty, Alexander Bishop.The[Toronto Maple Leafs signed Bishop](https://www.nhl.com/news/toronto-signs-college-goalie-bishop-as-backup-against-senators/c-326902998?tid=277548856), a goalie from the University of Toronto, to an amateur contract to serve as their backup before their 3-1 victory over the Ottawa Senators Saturday. The 24-year-old suited up in number 70, but didn't get in the game. Which is where Ayres offered his advice.[Tweet from @Davidayres901: They should���ve put him in lucky number 90](https://twitter.com/Davidayres901/status/1449510825060970497)Ayres[famously stopped](https://www.nhl.com/news/carolina-hurricanes-celebrate-david-ayres-anniversary/c-321710794)eight of 10 shots over 28:11 for the Carolina Hurricanes in a 6-3 victory over the Maple Leafs while wearing "lucky number 90."But No. 90 was cool long before Ayres wore it.In March of 2018, Scott Foster - a then 36-year-old accountant - got his big chance when he donned No. 90 for the Chicago Blackhawks and became the first EBUG in NHL history to make a save. Foster stopped all seven shots he faced in the Blackhawk's 6-2 win against the Winnipeg Jets.[Tweet from @Davidayres901: I wasn���t just talking about me. Seems to be the lucky emergency goalie number. pic.twitter.com/fuZC3SvZOM](https://twitter.com/Davidayres901/status/1449516280839553032)Foster[stepped in for Blackhawks](https://www.nhl.com/news/emergency-goalie-scott-foster-enters-game-for-chicago/c-297467924)when then-starting goalie Collin Delia - who filled in for an injured Corey Crawford - went down early. Delia was credited with the win, so two years later, Ayres made his own history while also wearing No. 90.There must be something to that number.
