Jiricek would be sweet but I think other team's would throw together sweeter packages. I'd do Robertson, the 2027 2nd and Dewar.
Kreider would also be sweet but he wouldn't be cheap and there's no real way to make the money work since I doubt the Rags would take the 2026 1st, Jarnkrok, Niemela, Robertson and Benoit. They'd want that 1st, McMann (very similar player), Minten/Cowan and Timmins which I think makes us worse.
I wouldn't be opposed to trying to get Kakko for a song, though. He's obviously not performed to his standing but he's good on the boards, responsible and can evidently play some reps at C, you're gonna tell me there hasn't been mismanagement there?
