So to be clear, you’re saying that you think Ferraro will turn it around?
I can’t speak to the players traded from the Sharks or developed before my time (Stuart, Hannan, Carle, young Murray), but none of the others struggled the way Ferraro is struggling.
I was always a fan of Ehrhoff, Demers, and DeMelo. They may have been “struggling” according to the coaches and fans at the time, but the numbers say otherwise. All three of those guys were top-4 defenseman (in my eyes) when they were traded from the Sharks. Vlasic plateaued, but he was still a very good second pairing D when he was rumored to be available (the great Ehrhoff vs. Vlasic debate). Braun too never really struggled, just stopped progressing for a year (mostly due to playing with Colin fricking White and/or Kent Huskins…) before continuing his development.
Ferraro is truly sub-replacement level right now. Like, if it weren’t for his name, his draft pedigree, his history, and the fact that he’s well-liked, he wouldn’t be in the NHL. None of the players you listed were ever as bad as Ferraro right now.
