We have no idea what Verbeek's expectations are, what was communicated to Cronin, and how Verbeek evaluates Cronin's performance. I think Cronin could meet Verbeek's expectations and still be let go if Verbeek was always clear that the idea was for Cronin to come in for two years and set the culture before moving on. For all we know, that was the plan.
There's no way Verbeek looks at the last two seasons and says, "Yes! This is what I want." Any fan with an internet connection can see that the team is, in many ways, still struggling but has a better W-L record largely because of goaltending. That's not sustainable, and Verbeek has to know it.
So two things could be true: 1. Verbeek likes the work ethic and defensive habits Cronin has taught, which is what Cronin was brought in to do; and 2. Verbeek realizes that Cronin is not the guy to take the team to the playoffs. In that case, I think Cronin gets let go if Verbeek's next coaching target is available and willing to come to Anaheim.
