McElhinney could have been much better.
Do you think it's good not to play for 2 weeks? McElhinney did that often.
Do you think a team plays better when they played the night before? 13 of his 15 starts were team b2b games.
This mess didn't use him to his strength. McElhinney was unwanted, only a slave to play at bad times.
It was a mess for Reimer and Bernier too.
I hope CAR will use McElhinney better but I have doubts, because how they used Darling.
Your questions appear as though they're being asked on behalf of a starter, which McElhinney is not and never has been for the entirety of his NHL career. As a back-up, not playing for two weeks and then starting or, playing the second of a back to back, or first, depending upon the team is precisely what McElhinney was picked up from waivers to do and do effectively. And so the tone of your questions likewise demonstrate a complete unfamiliarity with who McElhinney is and what the definition of an NHL back-up typically requires.
Reimer and Bernier and McElhinney are not interchangeable goalies when considering their market value or positional history, with Toronto and within the NHL over the course of their careers.
Toronto last season, in comparison to Toronto every season previous to last season, can't be understood as similar situations and environments as something equivocal year over year and indistinguishable one from the other. So much so that the season you're calling a "mess" was a historically productive year, with respect to regular season points.
What I get from your post though, is that you're a big McElhinney fan and hope the best for him in Carolina. And that's great. I suspect most Leafs fans want the best for McElhinney as well given what a solid job he did as Andersen's back-up.
