Not every team you think is going to make playoffs will, and I'd even take a guy playing his off side as a LH shot over Ceci on this team come playoffs.
I'll run through every possible option for you.
Anaheim - Cam Fowler 1 year left, Dumoulin pending UFA. Not sure if Dumoulin is an upgrade, I know he used to be but haven't followed him since his time with the Pens.
Calgary - Andersson 1 year left - RH shot, definitely a massive upgrade on Ceci.
LA - Gavrikov - LH shot, LA could very easily miss this year
Seattle - Larsson RH shot, could very easily miss this year
Vegas - Theodore LH shot, but plays the right side as well. Could easily miss if they get into injury troubles or if their goaltending gamble falls apart.
Columbus - Provorov, LH shot but an upgrade on Ceci
St. Louis - Nick Leddy 1 year remaining, LH shot but and upgrade on Ceci
Winnipeg - Pionk, RH shot. Someone might drop out of the Central with Nashville's retool and possibility of Minnesota bouncing back.
Pittsburgh - Pettersson - LH shot but upgrade on Ceci
Washington - Chychrun LH shot who can play R side. Not sure I'm sold on him but might bounce back this year.
Buffalo - Jokiharju RH shot. Possible upgrade depending how he continues to develop.
Detroit - Jeff Petry - not sure if he's still an upgrade haven't watched him recently.
Montreal - Savard (not my favourite pick but probably still an upgrade), Matheson LH shot 1 year remaining.
There's options out there for sure.
