It sounds a lot like you're questioning whether he can handle life on the road in the low minors. And believe me, I know it sucks. When I was a day-to-day fan of that league, we heard about stuff like the Knoxville Cherokees getting stuck in a blizzard, putting on their skates, and skating down the highway. Players who effectively had no "home" to speak of, per the joke upthread. Players with all sorts of issues that would have made them completely non-functional in the NHL. It's not an easy life, by any means, but it's also not necessarily harder than the rigor of an NHL lifestyle. Again, a lot of guys who would be non-functional in the NHL manage to function in the ECHL.
As far as development, playing against ECHL competition temporarily shouldn't be an issue. Ned has been there before for a handful of games, specifically to give him a taste of the professional game. For a 20 year old kid, there are worse things than to be around a bunch of guys who are absolutely desperate for an opportunity, playing hard and spilling blood in front of small crowds to chase their dreams, while also being held to professional standards. He's coming from a context where players are billeted and treated like high school sports stars, so a brief stay in the low minors would serve as a transition period to drive the point home... this is the real thing, it's not going to come freely, work your way up from the bottom.
As long as he ends up in Charlotte (assuming he earns it) by the end of the season, I don't see it as anything especially detrimental. If he's still there to start next season, that's a different story.
