I agree that they could use a Center until their young Centers are ready to play big minutes.
One guy they should consider is Toews. He’s older now yes, but I think if you give him Gaudreau and Laine for wingers, he will do just fine.
Toews only has 1 year left on his deal so that’s a plus. Obviously cap retention is needed. I could see something around Toews and 50-60% retained for Roslovic.
That would actually make a ton of sense, the fit is almost too perfect, yet I doubt many will take it seriously because of Toews' hockey acumen lately being dismissed for being $5M overpaid.
Of course, Toews has an NMC to waive.
But, him between Laine and Gaudreau, playing the "defensive" presence could be huge for the Jackets. And the ask from Chicago can't be that bad, they'll probably want some sort of future. As you suggest, perhaps a Roslovic would fit well? And since Columbus is the one most in need of doing the trade, maybe a sweetener like a 2nd or 3rd rounder?
