I think to make it interesting, we should exclude Lemieux and Gretzky for this discussion. With that said, here is my top 5;
1. Sakic 1995-96: 120 Pts in 82 games in the regular season (3rd overall) and then 34 pts in 22 games (including 18 goals) in the playoffsto go along with the Conn Smythe.
2. Doug Gilmour 1992-93: 127 Pts in 83 games in the regular season (2nd in Hart voting and won Selke) and then 35 Pts in 21 playoff games to finish behind # 99 in playoff scoring only.
3. Bernie Parent both his 1973-74 and 1974-75 seasons, 47 and 44 wins apiece and 2 Conn Smythe trophies and 2 Vezina trophies. (I'm giving him the 3rd spot for both seasons).
4. Bobby Orr 1969-70: won Norris, Art Ross, Hart and Conn Smythe trophy (only player to win all 4 major awards in the same season).
5. Malkin 2008-09: Art Ross, 2nd in Hart voting and Conn Smythe
HM: Paul Coffey in 1984-85, Hasek in 1997-98 and 1998-99, Tim Thomas in 2010-11, Pavel Bure 1993-94, Jagr in 1995-96, Eric Staal in 2005-06, Mike Bossy in both 1980-81 and 1981-82, Trottier in 1979-80 and Sergei Fedorov in 1995-96.
