If the Blues wanted to move on from Allen in the middle of the season, trading for Louis Domingue would be a great start in ensuring that your backup goalie situation will be handled correctly.
Domingue is in a predicament with the Tampa Bay Lightning as he has found himself in the middle of a goalie surplus. The Bolts have arguably the best goalie on the planet in Andrei Vasilevksiy and the team also signed former Hurricane Curtis McElhinney to a two-year deal this offseason.
The 27-year-old goaltender will likely have to find himself a new organization once the season starts and teams get a better look at the goaltenders they have now, but don’t let the fact that the Lightning will let him go fool you, because he is a viable backup.
Domingue was drafted by the Phoenix Coyotes in the fifth round of the 2010 NHL Draft and spent the first four and a half seasons with the Coyotes before being acquired by Tampa Bay in 2017.
The Quebec native has a career record of 55-49-8 and has allowed 2.96 goals per game and has stopped .907% of the shots he has faced in 122 career games.
His career with Tampa has been much more beneficial than his stint with the Coyotes. It may be a result of playing with a better team, but in his two seasons with the Lightning, he has posted a 28-8-1 record with a .910 SV% and has allowed 2.88 GAA.
Domingue and McElhinney were one of the main reasons why I would have been okay with the Blues trading Allen this summer. There are plenty of viable goaltenders on the market, and with the goalie cluster in Tampa, Domingue might come cheap.
