I think a team like Carolina could use the Cat. They had so much trouble scoring in the playoffs. Nobody with the great in tight hands like the Cat has. Cat would have better numbers on the 1st line there than on the 2nd line like with the Sens.
Not sure what the package would be, as Canes' 1st rounder is very late, and probably will be next year as well. Maybe 2 1sts. Sens downgrade from what they paid as 1 year of ADB is worth less than 2 years.
I think the Sens should trade him whether he wants to sign or not. They have lots of scorers, his spot will be taken by Norris on PP1 next season. I'd rather spend the money on a goalie, better 3rd line, and/or save money for signing Sanderson and Chychrun in the coming years, more important than the Cat.
Sign and trades are so rare, I won't even consider it.
People say the Sens have no leverage, but they don't have to trade him in the summer, they could easily trade him at the deadline probably for a similar amount. One good thing for Sens is the total lack of scoring free agents available this summer. If someone wants a scorer, Cat is one of the few options available.
