I was referring to Ward, and [to a lesser extent] Kunitz. Manning would probably get a look from other teams, if only cause of his age and #GRIT and #TOUGHNESS.
I have no idea if Kruger can still go, but if he can, there's no question he's a better, more impactful bottom 6er than Wingels, as he can/has played more minutes, against tougher competition, in tougher starts. Whereas Wingels was trusted only against the other team's weakest players, and provided a marginal upgrade in scoring for the trouble, all while the rest of the lineup saw tougher competition and less production as a result.
That's not entirely Wingels fault, he was just one piece of an idiotic plan to ice a 4th line model that was obsolete years ago. But it's clear this team needs somebody that can share the load on tough competition, not spend 8 minutes a game against other 4th lines.
I'd much rather take the chance on Kruger and let Kampf learn on the job on his wing to become the heir apparent, then spend another season with a retrograde obsolete 4th line model that hurts every line above them.
