This is a move that has potential to bite Ottawa in the ass if the Rangers can figure Puempel out, but it probably won't. There's a chance that a lot of this could be wrong place wrong time for Puempel as a goal scorer because he is on a team where right now nobody at all is scoring.
I'm still not sure Puempel got a fair shake in Ottawa, but at the same point, they seem to be taking a hard lined mentality that the NHL isn't a development league. So giving him half a dozen games on Brassard or Turris' wing to see if he can really click regardless of whether he "earned" them wasn't going to happen. Even Ryan Dzingel didn't get sustained top 6 time off the bat. Dzingel was up and down the lineup all throughout the start of the season but excelled almost every where he was made to play. For the most part Puempel didn't look out of place as a 4th liner, but I would not say he excelled.
Especially with another team entering the league, I think Puempel will carve out a career as an NHLer for the next few years. It is more likely that career will be as a depth guy and not a 20 goal scorer. The reality is if Boucher wasn't going to push him up the lineup, and guys like McCormick can play the 4th line role better, while a guy like Lazar comes into his first game of the season and despite being sent to the AHL while also missing extended time with mono completely outshines Puempel, it might be time to move on.
The Rangers are 3rd from the top, so that means only Chicago or Montreal could have claimed Puempel. Although I did not think he would have cleared waivers, from this it seems like there is a good chance had it not been for Zibanejad's injury, I would have been wrong as he might have cleared. For those thinking this is a big mistake for Ottawa, or shouting "asset management", when someone has no value, there's not much you can do to manage that asset. When you consider that 26 teams before the Rangers passed on Puempel for "free", it is fair to imagine that if Dorion shopped Puempel prior to waivers, there would have been no takers.
