*Looks at RHD thare are pending UFAs on non playoff teams this year*
Ya, that "someone" doesn't exist...
There's no Tanev this year, not even a Walker. If Ceci was available at the deadline he'd literally be at the top of the list around the league for teams needing RHD.
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.
