Quoting: BeterChiarelli
NHL upside yes, but don't expect any of those men beyond Del Maestro and Allan to have top-4 upside. This very much seems like a case of getting excited off of your own pool of prospects - nothing wrong with that - but these development curves are hardly linear. The point you're missing is that Chicago wholly lacks the roster support to be anything beyond a lottery team over the next three seasons. The Hawks still need pieces today to help grow the players of tomorrow.
Alternatively, try looking at this from the assumption that all of the names you listed could develop into a top four role: what pieces are here now to help get them from prospect to prize? If the name of the game is to prevent young players from taking on more responsibility than they're currently ready for, why to the Blackhawks currently employ zero NHL LHD? The bin of skaters left is uninspiring but could get the Blackhawks by for another year, while insulating one or two young defenders at the bottom of the roster and leaving miles of open ice for the prospects in the AHL.
Acquiring Lindgren next offseason continues to solve that problem without leaving the Blackhawks saddled with a functionally useless contract. He is young enough that he can help bring the Hawks to contender status and still be a middle-of-the-roster piece. Even by way of offer sheet would be fine, but I wouldn't consider this a realistic option because they never happen.
Quite honestly, take a run at Dahlin or Sandin if that better suits your fancy. Lindgren's name only came to mind because the Rangers are going to be in serious cap hell post-Miller extension so the acquisition price should be reasonably low. The overarching issue remains the same and acquiring any solid top-four to top-pair piece only serves to do the Blackhawks good. I didn't realize this was a point of contention amongst yourself.
No offense, but you obviously don't know what you're talking about when it comes to CHI's pipeline, coaching, or rebuild plans. This has nothing to do with being high on my own pool, and everything to do with what Davidson has clearly stated they want to and are going to do, as well as what they have demonstrated so far. If you consider those things, the plan is quite obvious.
Phillips has legitimately been one of the best all around left shot defensemen in the AHL the last two years and is only 21 years old. Vlasic has shown, albeit in a small sample size, that he can defend effectively against high end NHL talent. Also in a limited sample size, Kaiser came in at the end of last season straight out of college and looked like the most polished and ready defensemen I've seen come out of CHI's pipeline in a very long time, like he could legitimately be a difference maker. Allan is probably the biggest question mark of them all, although I like him a lot more than he gets credit for. I have very high hopes for Del Mastro, he seems like the most natural leader, great communicator on the ice, plays big minutes, big body, strong defender and has some legit offense to his game.
I'm not saying any of them are a sure thing to become top 4 defensemen, but we have way too many LHD to work through over the next few years as it is without expending assets on veterans that would essentially have no place in the future of the Blackhawks and creating roadblocks for our young LHD to come in and learn the NHL ropes and prove themselves. It would be counter productive. The players and coaches that will help them along are already in our system. They are big boys and they will be fine. I could certainly see them adding one defenseman on a one or two year deal or taking a cap dump LHD like Martinez, for example, to eat minutes, thus leaving only two LHD slots for the younger guys to fight over, but they certainly aren't going to pay for them in a trade. I'm sure at some point during camp or the 23-24 season it will become a lot clearer whether we need to do that or not. But if what we've seen from guys like Vlasic, Kaiser, and Phillips, so far, is any indication, they won't need to. They just need to give these guys NHL opportunities and legit ice time and they will come along just fine.
