If it was Ladd I'd say the deal would be done. Wheeler is a good guess though.
Ladd is 28 and only locked up for 2 more years then is a UFA.
Kadri is just entering his prime and is team controlled for 4 more years with next year at a very affordable cap hit.
Kadri has more value in my eyes when contract and that he plays center are taken into account. If we're trading Kadri I'm expecting a center under 25 who brings more of an all around game or is almost assured to project to like a Couterier, Schenn, Lindholm, Stepan, ROR with Adam Henrique being the one name I'd watch out for.
Jersey desperately needs help on offence. Henrique is 24 and locked up for 5 more years at 4 million. He doesn't have the offensive upside of Kadri but he can be used in all situations unlike Kadri. Personally I take Kadri and his upside in a straight up deal but other pieces could be thrown into the mix like a younger Dman in Fayne, Larsson, Gelinas,
In the end if Kadri is dealt it'll be a youth for youth type deal with multiple years of team control. Nonis has stated he isn't going for short term fixes.
