Ha. A whole lot of yikes going on in here.
Both guys are fairly equally up for grabs in the sense you don't really want to lose either one... but it depends on what the team we're trading with values more.
I would say Kadri is the easier one to deal. The contract is easier to move. He's older. For as quiet as his season was relatively speaking he was still productive. They have a little less pressure to really hit a home run in the trade because we pretty much know his peak. He can play 3rd and maybe be a 2nd line centre if you can find a way to motivate him.
But if they get that fairly young RHD legit top pairing guy for Nylander you do that and try to forget we had to keep Marleau instead because we haven't seen his full clip with this group.
