Very few people would consider Pietro a stud anymore. He's still a good-great defenseman both most dont think of Pietro when they bring up Makar, Fox, Hedman, etc.
VGK seemed to have better depth of GOOD-GREAT players (Pietro, Theodore, Stone, Eichel, etc.) and less of the game-changing elite players (McD, Draisatl, Matthews, Makar, MacKinnon, Fox, Kucherov, Hedman, Crosby, Pasta, etc.).
Flyguys have a forward and goaltending group (prospects included) that possibly mirrors VGK development. And you're right, defensively work needs to be done...that's why I'm hoping for a dreadful season and another Top 5 pick
