I dont think Seider has regressed and I believe he's one of the few "bad development proof" players given his track record of instantly being an absolute stud right off the bat at every level (including NHL) he entered.
I just really want this issue of having one top pairing guy, one middle pairing guy, and 5 #6 defensemen solved (easier said than done) so that his utilization doesn't have to be so damn ridiculous. Edvinsson needs a top 4 role, and we need to bring someone else in.
Trade Maatta for a 7th or something, let Ghost walk (love what he did this year but it's absolutely not a need if we get other top 4 dmen that free up PP time for Seider), I think AlJo needs to be waived if we don't have a roster spot for him (could be wrong but I feel like I read this somewhere?) so start him on the bottom pair with Chiarot, choose one of Holl/Petry to be the #7 guy and figure out whatever is necessary to do with the other one.
