It is an imperfect stat, but he had the same amount of giveaways as Lizotte but both were basically equal in takeaways for a net wash. Pretty good takeaway numbers from them as Lizotte does it with doggedness and Wagner does it by getting in with his speed on the forecheck.
I will say it is a lot easier to remember a blind backhand pass in your own zone that winds up in the net v. a play where Wagner's forecheck or pressure led to a goal. It's like me remembering my bad gambling beats much more than my big wins.
I disagree that he is gone once the prospects are ready because:
a) When is that?
b) Who is that taking his place?
Maybe I'm missing something, but I don't see many prospects in the system built to be 4th line wingers. Not all of the prospects will make it, obviously, and I think Wagner is still above Prohorkin, Amadio, Moore. Even with a fair amount of the prospects making it, there will be other vets that are gone as well. Like, I'm hoping a prospect takes Frk's spot eventually v. someone like Thomas or Fagemo only becoming an 11 minute a night player.
You're right that he isn't a brain surgeon out there, but he also has to be up there for quality chances per minute played, if that is even a stat. The Kings want to be faster so I think they would want to hold on to their fastest player, especially when that speed isn't found in a 5'7" midget.
