Nice try, but Jack Campbell does not compare in any way with Hellebuyck. He had a .892 save % over several years in the OHL and a multiyear .917 in the AHL.
Hellebuyck set an all time save % record in the NCAA (just under .950) and backstopped an atrociously poor Ice Dogs team in the AHL with a .921 save % in his rookie year.
Slightly OT, but the affiliate was named the IceCaps, not the Ice Dogs.
