Albert Johansson is a better skater and probably a better defender than Boqvist. You should have seen the night and day difference between the start of his year and end of his year in Grand Rapids. Ben Simon was basically coaching the skill out of the entire team and the team defense were chipping it off the glass or dumping it to center even when there were clear breakout lanes. I've seen house league hockey with more structure than Grand Rapids last season.
And I get that anyone in the #4 defense spot will have some flaws. But if I'm chosing a #4 defenseman I want someone that can be relied upon to move up the lineup a spot if there's an injury.
Scott Mayfield? Ryan Graves? Luke Schenn? These guys aren't offensive dynamos but they also aren't liabilities and can be relied upon to play 20+ minutes and can put up 20-25 points. THAT is what this team needs.
This team can rely on Seider, Walman and Edvinsson to be puck movers. Maybe Wallinder or Johansson when they make it. Once Detroit stops fishing the puck out of their own net with so much frequency their offense will get better as well.
I'm open to Mayfield, with Severson off the board I think he has more attractive suitors who don't play non-competitive hockey in a small midwest market. Maybe you can outbid if you're willing to overpay a bit, I don't hate that, but again no guarantees with UFAs. Graves is a decent player, shoots left which wouldn't be my preference when we're already likely playing at least one lefty on the right side. Schenn is a fine plug for a year or two, I guessss, it really doesn't get the blood pumping. If our blue line change this year is replacing Hronek and Lindstrom with like Edvinsson and Schenn or someone of his calibre, that's not exactly driving the team forward.
On the other point, I don't agree that Johansson is a better skater than Boqvist. If he is a better defender, and it's tough to gauge because he's playing against weaker competition, it's pretty marginal. I don't see 6'0 185 Albert Johansson killing penalties super effectively in the NHL. We can hammer the Ben Simon point all day long, but a guy who is producing > .3 ppg in his D+4 in the AHL probably just isn't going to produce points at a high level in the NHL. Johansson's a nice skater but ultimately he hasn't added anything else to his game that suggests top 4 NHLer.
