No offense but him playing with Ekholm would actually make me concerned of just how bad his defensive game really is. Ekholm can pretty much make anyone look good, he has been doing it his entire career, which is why I said for years if I had to pick a Dman first it would have been Ekholm and not Josi.
A guy like Ekholm also allows him to play a more offensive game, he won't have that guy to play with in Nashville, and we definitely don't need another Dman that is all offense and no defense.
2ndly all the Bouchard talk doesn't really matter anyways, Trotz has always said he wouldn't trade him for anything but a game changing type player, and he ain't on that level.
