I don't think Detroit's performance changed the timeline as much as COVID did.
Yzerman pretty clearly built the team to suck last year and this year. His contract structures were clearly set up to give him a whole lot of room to move in the upcoming season, but I think with most teams feeling pressure to fit under the COVID cap, and the opportunity at three big-time centers in 2022, he's going to once again weaponize cap space for picks and prospects. Also, it was pretty evident that Seider was going to be on the team this year, and likely Veleno as well. COVID prevented both from happening, minus a cup of coffee for Veleno.
Going forward:
Larkin - If he's not on the team it'll be because he left in UFA. I do not see Yzerman trading him. I just don't. People forget that Detroit sucked for several years while Yzerman was captain, and didn't win his first Cup until he was 32. Larkin isn't nearly the player Yzerman was, but he can still be Landeskog type captain where he's the clear leader but not even top 3 on the team.
Bertuzzi - Back injury leaves things up in the air a little bit, but I don't see Yzerman trading him unless he gets blown away with an offer. We know from watching him draft that Yzerman loves the guys that have a high compete level. Bertuzzi is already rare in that he's an agitator who can drive offense, but he's also one of those players that can completely change the momentum of the game and energize his teammates. That's a quality you don't teach or develop, and one that you need when you're in the playoffs.
Vrana - I think people read a little too much into his success here and forget that a third of his production was in one game. My sense is still that Vrana gets moved similar to Mantha, if not in this deadline in the next one, but I could be wrong.
Zadina - The poor guy has never had a steady spot in the NHL. He just bounces between linemates and is now handcuffed to a defense-only system. I think long-term, this season will actually be good for him. He looked super-well rounded. If he can tap back into that offensive potential, I think he can be a poor man's (30-30) Mark Stone or Marian Hossa.
Fabbri - He's been good when he's played, but his time is coming. He's a cheap option that'd be a great addition to boost a team's 3rd line going into the playoffs. I expect to see him moved at the deadline, probably with retention.
Hronek - Will be massively relieved by not having top defensive responsibilities going forward. You might get to see his offensive numbers increase simply because he's getting OZ starts and Seider's getting DZ starts. May not happen immediately, but in the coming years, that's inevitably where we're headed. I don't see him getting moved.... Unless we draft Brandt Clarke.
As for the U23 guys:
Seider - Makes the team out of camp. People need to be realistic on their expectations though. It's incredibly possible that he plays safe hockey while he feels out the league. ESPECIALLY if we're still running Blashill and Blashill is still running a defense-heavy system. It's also hard for him to join the rush on a team that sucks at offensive zone entry. Seider plays two very different games. He can turn on the offensive switch when he wants to and just as easily shut it off and play lock-down defense. I mean that in a good way, but I think there's a strong chance you see lock-down defense Seider to start his career.
Raymond - Don't see him getting more than 9 games. Frolunda is a good club, but their emphasis on using all four lines kinda held him back. He can benefit from being, "The guy", offensively in GR for a year, getting top line minutes and big PP time while he gets acclimated with smaller ice.
Berggren - Also don't see him getting more than 9 games. And people need to be careful about letting their expectations get out of hand with Berggren. It's probably a lofty expectation to even suggest that he becomes a new Nyquist, and we should be happy if he does.
Veleno - I see him as a 3C, long-term, but that's not a bad thing. He's not a Darren Helm 3C, he's well-rounded AND actually has scoring talent.
Rasmussen - I don't see him being a 2C either, which begs the question of, does Detroit play him on the wing, or do they trade him or Veleno? I don't think you get much out of either in terms of futures, but I do think they could be a valuable piece in a package for something bigger.
Svechnikov - Has no future here, and it's been clear for quite some time now.
Cholowski - I don't see much of a future for him either. Guy is a complete dope when it comes to playing in his own end. He's like a poor man's Brendan Smith, and Brendan Smith sucks.
Smith - Deserved to stay up. He's never gonna be an offensive force, but he's absolutely a guy you need on your team to beat somebody's ass when they come after your top forwards.
