Yes, for sure.
It's just basically a 'more now' or 'less later' situation. If NJ is fine with that then no problem, that is their call. Can really only base a proposal from the Canes on the situation right now though. It seems like it's fairly close in terms of value and mutual interest and really that's about as good as you can get on this board. I'm not here to convince every NJ, CAR, or neutral fan that the deal should go through.
I think your points on keeping him until next season/deadline are fair just pointing out that the return is likely less than it would be right now with the extra year of control.
