I'm pretty sure Buffalo would pass on that deal. There is no way they give up ROR, Risto and a first for 2 middle pair defenders, an ok starting Goalie and a bunch of spare parts.

They would be better off just trading ROR for a top pair D and keeping their first round pick.

Parayko a middle pair defender?
Hahahahahahahaha
ROR isn't worth a top defensemen anyway

There is absolutely no way Panarin is sent to the Blues without us getting Tarasenko back. We sure as hell aren't trading the best scoring forward this franchise has ever had for a bunch of depth players and futures.

Or would you accept a deal of Tarasenko for Dubinsky, Abramov, Broadhurst, and a 1st?

If he's says he's not resigning with you at deadline. That's a hell of a deal.

Still CBJ is going to give him the check book. So you'd have to pay full value. He also seems to like it there.
I'd love to have him! Just won't ever happen, he's going to be a CBJ for a long time

Parayko, C., Allen, J., Steen, A., Walman, J., Nurse, D. & 2019 2nd round pick (EDM)
for O'Reilly, R. Ristolainen, R & 2019 1st
O'Reilly, >= Parayko, C
Ristolainen, R > Nurse, D (his point production has been improving every year)
2019 1st > 2019 2nd
Walman, J. an OK defenseman prospect
Allen, J., a decent starting GK with a descent cap hit
Steen, A., brutal cap hit for his production with 3 years left on his contract.

I like the idea of getting 2 young defensemen Right and Left, IMO the 1st kills the deal. I see Steen as a partial cap dump, Allen is not what Buffalo needs, and Walman is a "B" prospect. So IMO Buffalo would say no.

He plays middle pair minutes...
Most of the trades proposed for ROR is a top pair D.
