Had Scott Niedermayer retired before he signed with the Mighty Ducks of Anaheim, he might have been a Hall of Famer as is.  He had already won three Stanley Cups and a Norris Trophy as a New Jersey Devil, but the Defenseman from Alberta had a lot left, and he removed all doubt after his five seasons in California that he was a Hall of Fame player.

Jean-Sebastian Giguere was a First Rounder by the Hartford Whalers in 1995, and he played there briefly before he was traded to Calgary.  Giguere did not accomplish much as a Flame, so most people likely didn't think much of it when he was shipped off to the Mighty Ducks.  The hockey world would notice him soon after!

Corey Perry debuted with the Ducks in 2005, two years after being drafted late in the First Round (28th overall), and he methodically improved annually, becoming one of the most well-rounded hockey players in the game.

One of the most gifted offensive players of his day, Paul Kariya, was the Fourth Overall Pick in 1993, and a year later, he was an All-Rookie for the Mighty Ducks of Anaheim.
