Don't think the Jets would be looking for a package for him. He's had a fantastic year and is being developed as a C which the Jets are lacking long term. the NHL is turning into a speed game and he's elite at that. The only other area of need is RHD, but I wouldn't have interest in a Casey for Lambert swap at all. He hasn't established enough value to ask for asinine return, but holds too much potential too not see what we have in him.
Basically, the only way I see him going is in a package for a young top 2/4 RHD with term. The only one on the Devils that would be of interest wouldn't be up for discussion understandably.
Back to Toffoli, I hope the Jets are interested, price depending. MTL 2nd, 25 3rd and your very own 6'8 D man who fights to counter Rempe?
