Harris isn’t a top 4 Dman. Sure he can fill it but he’s a top 6 at best. Overhyped.
At this moment, you're right. Harris isn't top-4 D material.
But the nice thing with prospects and young players is that they can still improve. You watch them play, they improve before your eyes as rookies, and if they look the part of true NHLers after 30-40 games, then you keep playing them, giving them opportunity in the hopes that your rookies show continuous progress.
Generally it takes about 200/250 NHL games before you can start really making definitive arguments about a young defenseman's career going forward. Until then you can see clues here and there as to what a young D will eventually become, but those are still incomplete, inconclusive given the lack of sample size.
And Harris was overhyped by/for whom? No one expected him to be a savior, or star player from the get-go, so I genuinely don't understand where you're coming from on this front.
The only angle which might be viable on this is us Habs fans' enthusiasm concerning our own prospects, and in that sense, EVERYBODY gets a tad overhyped. It's just the nature of the game and fandom in general. So, again, while your statement might be true in a wide, at-large kind of way, it also doesn't hold much (or any really) sway when it comes to Harris in particular.
Then you add in the fact that Harris has showed a lot of quality play thus far for a rookie, though he has had some issues handling NHL physicality and clearing the net/breaking the cycle that I will readily admit, and it puts the final nail in the coffin of your statement.
Here are some (small-ish players just like Harris) examples of growth leading to good/great careers in the NHL, taken amongst MANY potential recent-ish outcomes to choose from;
1) Brian Rafalski didn't look like a potential NHLer until the 1996/1997 season in Liiga, at 23 years of age. While he only made it to the NHL at 26 years of age and it took him half a season or so to earn top-4 icetime, he was ready, overripe and in his prime, with more than three seasons of pro, Liiga play (a time where it also was a higher level of competition than today) under his belt at that time in 1999-2000.
2) Ryan Ellis looked like a stretch to ever be able to play competent 5-on-5 defense until he was 23, in his third season with Nashville in '13-14. He improved his positioning, learned to defend the cycle better, as well as got stronger over the years. And this constant progression eventually saw him become a good top-4 defenseman for Nashville.
3) Matt Grzelcyk had to improve in various facets until he was 25 before getting the opportunity to play top-4 defense for Boston. He earned his chops through years of performing when it matters and improving in key facets including strength and defensive reads.
4) Nate Schmidt had to improve his defense and his decision-making with the puck before finally getting top-4 minutes and succeeding in his third year in the NHL with Washington, at 24.
Now, I'm not saying Harris will for sure, 100%, also dramatically improve and become a true top-4 guy for us like those guys became (and more in Rafalski's case). But we should still exercise patience when it comes to our young guys, and only move defensemen if we can fill-out areas of weakness elsewhere in our roster/prospect pipeline.
The last thing we want is to have another Eric Desjardins on our hands.
And Lane Hutson won't be ready next year, try 2024/2025 at the earliest, so we've got time still. Same thing for Mailloux, his defense needs AHL conditioning/training in a bad way (unless he improves like crazy in the summer).
So yeah, keep Harris unless we get an offer we can't/that would be stupid to refuse.
Oh, and as far as Farrell goes, you know, the one whom we really should be discussing here instead of Harris, I've loved his improved combativity along the boards this year, and the increased quickness with which he makes decisions in the offensive zone (also including how directly he now attacks the net on pass/offensive attempts).
Those are the two areas where I think he's improved the most this year (improved in every facet really, but those are the highlights of his season for me), and it could mean the difference between a middle-6 type of career in the NHL (ala Kerfoot), and one where he ends up being a top-6 option at wing for us.
Anyways, rant over. Cheers, and have a good day.
