Provided the Sabre's can negotiate an extension prior to the deal, I think it's win win for both teams.

Sure hope not. Great player in a cap world crunch

Still have reservations about moving the ‘23 first, but probably close if BUF can get get him under contract for 6-8 years in the 8-9M range

My play for the Sabre's is
Get Meier in this deal
Trade for Gavrikov and sign him to a 6 x 4.5
Trade for Gibson

Those three adds and this team is set for the next number of years

A little leery on Gibson based on current performance levels, and I don’t see GMKA making this kind of move with UPL playing well and Levi in the wings. As for Gavrikov, I see your point and while not my first choice, he does fill a need.

Gibson is suffering from playing on a porous young team. BUF has grown in their team game exponentially. He can pave the way for UPL and Levi to grow (UPL as a back up in the NHL and Levi in the minors) for the next couple years. And I think He'll come cheaper than expected.
I really like Gavrikov, and think he'd be a really good stay at home Dman for this team
