Offensively, Blashill said, Seider still needs to learn to think through plays before he gets the puck on his stick. He's able to draw defenders to him because of his size, but Blashill wants to see him move the puck quicker at times.
"Sometimes the right play is just, move it right away," Blashill said. "Just right away, knowing where you're going, let's play fast, let's get it moving, then you jump on the play."
"Just being a guy on the ice in all situations," Seider said during training camp, when asked what he wanted to show. "Moving the puck well, defend really, really well, I think that's what matters the most I would say in the first couple games, being really solid defensively and then offense will come automatically."
As for Raymond, the Swedish winger has more of an uphill climb to make the team - Blashill said during camp that he would need to be one of the better players on the ice throughout preseason to do so. But a quick glance at the roster for Thursday's game shows that Raymond will have a chance, as he'll likely get top-six minutes against Buffalo.
"He feels confident," Pius Suter, a potential linemate on Thursday, said during camp. "Yeah, confident. You can tell making those plays to the middle, getting a guy on his back. Looked pretty good to me."
Raymond also featured on the power play unit during last Sunday's scrimmage, with Blashill saying he can be of help there.
Still, both Blashill and executive vice president and general manager Steve Yzerman have been consistent in saying that, to make the Red Wings, Raymond - as well as any other young prospect - needs to do more than just prove he can play at an NHL level.
"To make the 23-man roster, well one they're young kids so I have no interest in seeing them in the stands in Detroit," Yzerman said before camp opened. "So they're really gonna be in the top 12 and even go as far as to say the top nine, which is a big ask. Because I want them playing meaningful minutes and being contributors."
