What a terrible image.
I don't think they can actually do that, at least to open the year. They're not cap compliant with Marino on the roster and they're 10 D deep before putting Trotman on LTIR. I'm not sure what impact Trotman has here, him being hurt complicates things.
I think the Penguins have 3 options:
1. Keep Marino in the AHL, have Ruhwedel as an extra D and be cap compliant
2. Send Marino to the AHL until rosters get finalized, put Rust on LTIR, get rid of Ruhwedel and call cup Marino with Rust's LTIR space.
3. Trade Johnson and you don't worry about the salary cap.
Once desmith is done and Rust and Trotman go on LTIR they can. They might finagle things at the beginning but for opening night they'll be fine. 12F, 9D and 2G with LTIR handling the cap. It's not ideal and if a forward can't go they can't do it, but they could make it work. It won't last and I suspect JR will be working on a trade but it buys them time.
