Now that Luukkonen is starting his rehab stint (which has been known as the plan for the last month since he missed most of training camp and all but one period of preseason) -- it reopens the questions around the number of goalies they have under contract.
Ellis has gotten 0 games -- Lyon has been great, but now your backup goaltender hasn't played in over 2 weeks -- and his next game will be his NHL debut and first ever on the ice with these defensemen. It's small potatoes, but it also has impacts with future trades/GM interactions, because STL had him lined up for a heavy workload and development with their AHL starting gig. If they get the chance to re-claim him, you've shafted him a month of development. They're likely less worried that you claimed him and more concerned that you're wasting his time. GMs are a small group and they're seeing you waste assets. Agents see this, too. Ellis' agent is increasing his Buffalo tax for any other future clients.
Georgiev has gotten 1 game -- because he didn't report to Rochester immediately. Leinonen has gotten 1 game, because Georgiev didn't report to ROC immediately.
Levi has only 2 GP, which makes sense because they were both back-to-backs thus far, but now you're also impacting his development time because Luukkonen has to get reps to resume his #1 (or #2 behind Lyon) status with Buffalo.
Ratzlaff has played 1 game with Jacksonville, but now will likely have his workload cut while Luukkonen is in ROC, which presumably would force Leinonen down to the ECHL.
This all goes back to:
Why did the preseason goalie signing (whoever it was) get a contract instead of a PTO? If it's an Adams Tax, then you call someone else. (Or hire a real GM.)
With a light slate to start the season in Rochester, why not let Levi be the backup in Buffalo? Maybe shuffle him once so he gets opening night with the Amerks and a free start in there, but otherwise get his GP in Buffalo until Luukkonen is fully healthy and proven ready to go.
Why bother to claim Ellis?
