You have to pay for a starting calibre goalie. The alternative is wasting your window on trying out different guys that you end up overpaying for (ie Dallas). You'd rather pay 9 million next year for Bobrovsky? 6-8 for a Varlamov, Howard, Talbot IF none of those get signed by their own teams? Roll the dice on a 35+ guy (Rinne, Smith, Miller) or an unproven guy (too early to say but we've seen it be guys like Darling, Talbot, Greiss, Lack in years past with varying success).
The Jets had no choice. Hellebuyck is real quality goalie. We consistently see the same goalies near the top of the league despite the claims of goalies are "voodoo". Yes goalies have cold streaks, even some guys have bad years, but there's no "voodoo" among the best goalies. Hellebuyck has the track record and NHL success. This is a fair deal for all sides.
