A lot of players had a great year in 05-06. Ovie himself scored +100 pts. The new rules being enforced quite strictly gave the players lots of PP.
Which is fine but yet only 2 players scored more than 110 Pts that season and nothing can take away from what Thornton and Jagr accomplished that season.
Also the very next year, scoring levels, especially powerplay scoring levels were not that much less than they were the year prior.
So if people want to discredit Thornton and Jagr for putting up 123+ Pts then they should as well Crosby in 2006-07 for putting up 120 Pts and doing it while scoring 61 of his 120 Pts on the powerplay. After all, there were 7 100 Pts scorers in 2005-06, and 14 total 90 Pts scorers in 2005-06 while there were 7 100 Pts scorers in 2006-07 and 14 90 Pts scorers in 2006-07.
For me the top 5 would be:
1. Jaromir Jagr, 54 goals and 69 assists for 123 Pts (2005-06)
2. Alex Ovechkin, 65 goals, 47 assists for 112 Pts (2007-08)
3. Joe Thornton, 29 goals, 96 assists for 125 Pts (2005-06)
4. Evgeni Malkin, 50 goals, 59 assist for 109 Pts (2011-12)
5. Sidney Crosby, 36 goals, 84 assists for 120 Pts (2006-07)
HM: to Joe Thornton in 2006-07, Ovechkin in 2005-06 (he scored 50 as a rookie and finished 3rd in league scoring), Ovechkin in 2009-10, Malkin in 2008-09, Henrik Sedin in 2009-10, Stamkos in 2011-12, Crosby in 2013-14 and Lecavalier in 2006-07.
