Yes

Maybe

how will Roslovic be any happier here on the 3rd line than in WPG?

That's a good question and a question Roslovic and his agent really shouldve thought about before the trade demand.
He wants more minutes, but the jets have Wheeler and Laine in front of him at RW. He wants to play C, but the coach didnt think he could handle the NHL responsibility quite yet. I do think there is fault in the coaching staff there for not giving him a legit shot at C when Little went out

We'll he ain't gonna get center here, and I don't see them moving Tanev down to 4th line for him. He's got 2 goals in 4 games.
People just ain't thought this through.

I think he has a chance to maybe move up into the top 6, depending on how people perform. Since Rust is PP1 and PK1/2, I could see them putting him on the 3rd and giving Roslovic the top 6 minutes for 5v5.

What makes you hesitate?

I like ZAR a lot

I get that, but we already have so many depth players. I really want O'Connor to get a chance. I get wanting to keep him though. I am not sure if WPG would want a Sceviour back or someone similar.
