yea, I think too much might be being made of this by some people...the whole "2nd line, 3rd line, yadda, yadda"....especially only being two games in.
You can bet the lines you see in the first 9 or 10 games on most teams are not the ones who will be regulars throughout the season.
Coaches need time to see what works, what doesn't, and also to see (along with the players themselves), who works best with whom.
Draft status, how much a player makes, or the expectations of the media and fans shouldn't dictate where a given player plays or how much, but rather the coaches in conjunction with the players and their performance on the ice.
That all said, hey, if young Hughes is gonna get his feet wet in the deep end (the NHL), what better linemates to have than Coleman and Simmonds....not the speediest highest rated players on the team, but certainly, not very many will be trying to take liberties or try to test Hughes on anything other than his hockey skill with those two on either side of him.
The cream always rises to the top, and unless the NJ head coach is going to be completely stubborn about things, I am pretty sure that if Hughes shows what he can do on an ice sheet against fully established NHL men, he will be augmented with more suitable linemates and ice time.
In a perfect setting, yea, I'd like to see Hughes in a top six role (maybe swapping him and Zacha), but too soon to really worry about his playing time.
