Alex Tanguay was chosen 12th Overall in the 1998 Draft and, as a rookie in the 1999-00 campaign, would score 51 Points. Tanguay had 77 Points the following season and helped the Avalanche win the Stanley Cup in 2001. Tanguay would have a 78 and 79 point year, respectively, in 2003-04 and 2005-06, but would be traded to the Calgary Flames the year after.
As you likely know, the first season of the Colorado Avalanche after the relocation from Quebec City would see them win the Stanley Cup. One of the mid-season trades that comes to mind that facilitated this was the trade from Montreal of superstar goalie Patrick Roy. The other, less talked-about one was from San Jose, the defenseman Sandis Ozolinsh.
Prior to signing with the Quebec Nordiques of the World Hockey Association in 1973, Serge Bernier had played for the Philadelphia Flyers and Los Angeles Kings and had done well producing a 50 Point Season for each of them.
One of the great young stars of the game, Nathan MacKinnon came into the National Hockey League as the first overall Draft Pick in 2013. As a rookie, the Nova Scotian Center would win the Calder Trophy with 63 Points. MacKinnon did not hit that mark over the next three years, but in 2017-18, he would have a 97 Point year with a league-leading 12 Game Winning Goals. He would also be named a Second Team All-Star and was second in Hart Trophy voting.
