Never. This is what happens when you bring young players in too early on defense. They focus on not making mistakes so they keep their spot and they never test their offensive skills against their competition and suddenly those skills regress rather than progress and their game takes that shape. A no risk defender with little offensive upside.
Sorry...i'm not buying this.
Neither Mete or Juulsen, even in the OHL and WHL respectively, has ever really shown an ability to be high point producing Dmen.
Juulsen had an impressive season points wise as a 17yr old, but that's mainly because he played on a team that had more offensive depth. The following year, that offensive depth moved on, and Juulsen's numbers suffered.
Mete's best offensive season in London yielded 44pts in 50 games...and this was in his D+1 season.
Maybe them not putting up points at this juncture of their NHL careers is because neither is ever going to be a big point producer, they're not going to generate offense on their own. As their junior statistics attest too, the points they put up is going to be circumstancial...and those circumstances are if the team around them has offensive talent...they're both good enough to get their fair share of points.
But on a team like Montreal, whose top scorer is unlikely to surpass 60 maybe 65pts at best...neither Mete or Juulsen is going to buck that trend and put up 50pts. That's not the type of Dmen they are.
None of this has anything to do with them being brought in "too early".
They are just not purely offensive Dmen.
Both have enough natural talent to put up 30ish points if the talent around them is strong...but to expect them to put up points on a team that struggles to score, is unrealistic.
