Ummm Yeah it is you need someone who can play on those lines and dissuade the opposition from even trying to run your guys. When Tom Wilson is healthy he plays on a first line there is absolutely a valid reason for that. The idea is to prevent not to engage. Those types of players are hard to find.That's not something we really need to address through top 6 or top 9 talent though. I'm sure they'll be looking to add at least 1 more tough guy through free agency(likely a 4th line guy) by the time that Edmundson's gone.
