Easy no from the blues

Gonna need to add quite a bit more. Especially if you're dumping Trouba

Blues really need puck moving D so unless youre throwing in a good prospect as well, I doubt they would take this. I like the idea of taking Trouba for 2 years with a little retention, even though hes really unliked league wide. Still a really gritty player that the Blues D is missing and him and Tucker on the ice together would be menacing if both healthy. Kakko I can see being a solid middle winger but if he really fell off as bad as everyone says he has (stats only say so much), then I doubt the Blues will want to take on a younger forward like him. Rangers are in my top 3 teams I see Blues working with this offseason either way.

Not for that.

This is honestly not that bad for the Blues. Sure the Blues might be able to squeeze out another later round pick. The other plus side would be more incentive to move ether Faulk or Parayko. Both of these guys could draw another 1st or multiple 2nd round picks.
