Source? Who wants a small 25 year old winger who can't kill penalties, isn't a defensive specialist and whose offensive skills are declining? He's one season away from being a permanent AHLer.
You'll still need 5 players to fill out that roster if the Leaves don't offer Ceci a contract, which is possible since he has arbitration rights. Considering how much of a hole Marner is going to blow in that $17 mil in cap space if they can dump the contracts you say they are dumping, what kind of players will you get for the other 4 the Leaves need?
Looking at Capfriendly, that current defence looks as scabby if not scabbier than Vancouver's. You thinking of ever winning a first round playoffs or even making the playoffs with that bunch?
