Anyone who was ecstatic with Zub's 2 year contract was foolish. Such a person must have looked strictly at the average salary and not at the length of the contract, which is far more important for a team that is just now looking to contend for the playoffs.
Zub is incredibly underpaid at 2.5M but losing him after 2 years would be a massive blow. Should have offered him a longer deal at around 5M per to get him signed long-term.
People can make the argument that he wanted to go with a short contract to maximize his value as a UFA, but Zub and his agent aren't stupid. They know that the most he can probably make as a UFA is something like 6M x 5YRs, meaning he'd make 35M over 7YRs after the bridge deal. Had we just offered him 5M x 5-6YRs out of the gate he'd be better off financially, even if he gets a big UFA deal.
From the sounds of it Dorion was pushing for a short bridge deal for Zub, given his comments about Lassi and JBD being able to step in and replace him after Zub's contract is up. It's rare a GM comes out and is so forthright about his plans regarding a player's future. It was silly when it was said a couple years ago when JBD and Lassi looked better than they do now, and it looks even stupider now that both look like bottom pairing guys in the making.
I've said this before, but RD is the hardest position to find in hockey. If you have the chance to lock up a top 4 RD long-term you do it, especially when it comes to someone like Zub who's game is based primarily on his excellent hockey IQ, not athletic ability that will dull with time. Chances of a long-term deal blowing up in our faces with Zub was low and it was a big mistake to not lock him up for many years.
If he doesn't re-sign I don't know what we'll do. Our D is getting exposed massively with him out, and there's zero reason to think we have prospects in the pipeline that can replace him internally. If anything we need to add another top 4 RD on top of him. If it comes down to it we need to overpay to keep Zub, even if sacrifices have to be made at forward to accomodate him.
