This move came as quite a surprise to fans today, as we very rarely see teams singing players so late in the season. The catch with this deal is that the contract doesn't start until the 2023-24 season, meaning Waeber is ineligible to play in the ongoing Stanley Cup Final.
Waeber would be the 4th goalie that Florida has under contract for the 2023-24 season, as Alex Lyon is on an expiring deal. This would seem to indicate that Lyon is on his way out of Florida unless the team plans on playing a goalie under contract in the ECHL, which we rarely see.
