Not really.
Kadri is NOT a difference maker. He's a complimentary player on a somewhat expensive, long term contract. AND some of the thinngs OP said as sought after in a return are much harder to find than Kadri.
Plain and simple: Finding a player of similar level to Kadri is easy. A team is going to spend premium assets to get "a Kadri".
I'm not comparing them other than maybe the element they bring to their team, but go out and find yourself a Brad Marchand (who is obviously way better than Kadri by a lot).....
Easy?
Nope, more like impossible. Getting guys like this when they are just entering their prime and still figuring out their place are just not available, because teams don't know they have them until they get there, and then they are worth more to the team they're on than what they could get from other teams.
Also, we should bring up that most fans hate these guys if they're not on their team. And they can't bring themselves to think how much they'd love and appreciate what they bring if they were on their team.
I hate Brad Marchand, but I know I'd absolutely love him if he was on the Leafs.
What is Brad Marchand worth? I bet the Bruins wouldn't trade him unless it was a kings ransom. They'll sign him to a brutal long high cap hit soon and they won't even second guess it. He'll look bad by the end of it maybe but those 5-7 years he was his best will be worth it.
Kadri is signed at 25 into his early 30's at $4.5 his prime years at a reasonable cap hit don't care what people think his trade value is he's not going anywhere and Babcock loves him. I kind of trust Babcock loving Kadri with all his issues and immaturity. He's a really moldable player that wears his heart on his sleeve from what I can tell.
