"Further within" would suggest Hughes has ever been in the Matthews/Draisaitl tier of players...
... That's not to say he can't get there, but he's just not at that level yet.
When he's been healthy, he's absolutely shown to be that tier of player in the last 2 years.
Before his shoulder injury in early February 2023, he was:
1st in ES goals
1st in ES points among forwards
3rd in goals (2nd among centers)
7th in points (4th among centers)
Through those 50 games, he was pacing for 57 goals and 110 points. Then he hurt his shoulder, and returned only 2 weeks later, still obviously not near 100%. By the 6 week point, he had seemingly recovered, putting up another 18 points in his last 11 games.
At the start of last season, he was leading the league in scoring through 10 games before again getting injured. Unfortunately, he again returned early and was struggling the rest of the season with his injury, to the point where he was pulled from the roster for nearly the full month of January, and then again pulled for surgery the moment the Devils were effectively eliminated from the playoffs.
His pre-injury numbers from the last 2 seasons:
60gp 40 goals 87 points
That's a 55 goal, 119 point pace without the benefit of a McDavid or Marner.
