I think it would help, but even then I'd still argue you want at least 3 solid D on any given defense, especially since we don't have a franchise level forward. Getting Powers gives us a potential anchor pair with him and Seider in a few years. That slots Hronek down to lock in the 2nd pair and maybe 2nd PP unit. Right shots are always hard to come by, so unless Clarke becomes our only good option at our draft spot I don't see the need to deal Hronek, and even if I do, then I wait at least until Clarke is ready to jump into the NHL. You don't want a D filled with 18/19/20 year olds. Having some age spread is a good thing. Dmen typically peak later (unless they are offensive phenoms like Karlsson/ Makar/ QHughes) and play longer.
Hronek was 36th in D scoring. He also led the team in scoring. The only dman above him on a worse team than the Wings was Seth Jones (Clb), additionally if you want to go bottom 10 (ie the non bubble teams) you only add Chychrun (AZ), Hughes (Van), Chabot (Ott), Burns (SJ), Doughty (LA), Reily (Ott/Bos). It should be noted that Hronek is the only one outside Doughty that didn't have another dman in the top 60, and even Doughty had a teammate come in at 65. The wings nearest support was DDK at 111. For those making the greater playing time argument, please note that guys like Mantha, Larkin, Zadina, Fabbri etc. also benefited by the lack of competition and yet they did not produce nearly as well. Larkin, our top scoring forward, finished 76th among centers, not even forwards. The fact that Hronek still continued a very solid 0.5 ppg average on a team this offensively inept is really impressive. I mean to put it into perspective Vrana, who finished with 19 goals, was all of 4 points away from scoring more goals than Larkin had points in a season.
Don't get me wrong. I don't think Hronek is going to top out at as your ideal #1 dman, but I think he is very much a Kronwall comparable guy. You don't throw those guys away for a shot at mid round 1st. Most prospects never make it to the NHL. Hronek is very much within our build window still. He is a Right shot which is something we've lacked for years. Thanks to the covid shortened seasons and flat cap I think we have a chance to lock him in at a pretty reasonable deal/ salary that will allow us to fit him in when a guy like Seider is making the big bucks in a few years. He also gives us some buffer for Seider and this years likely top pick.
