Yeah, Keith has been poor. Clinging to the fact that he had a similar start last year and was able to right the ship (not saying he's an elite #1, he clearly has slipped). Murphy was mediocre, at best, too.
JC has repeatedly stated that it's an open contest for #1G. Lankinen will stay on the taxi squad all season, most likely, as he doesn't have to clear waivers. WRT drawing in, it doesn't matter if a guy is on the active roster or taxi squad. And, yes, to your point, goalkeeping has been rather poor.
