There's a couple reasons why we probably can't start Cory in back to back's this season, like we did last year.
Because he didn't have to face 40+ shots nearly as many times last year as he has this year, nor even 30+ shots. So it was easier to throw him back in there the next night, with a much lighter workload the night before.
Another thing is that Kinkaid was awful all season long last year. He's never had a game that was nearly as bad as tonight, but he had too many stinkers last year. He's been solid this year, up until tonight, which was the worst outing of his NHL career.
He allowed 6 goals to Pittsburgh last year and maybe a few other times, but he usually wasn't destroyed for multiple bad goals even in those blowout games.
