I personally feel that Aho has a higher chance of reaching 100 points than Laine. At least for now.
But I presume Laine will spend this summer working on his speed and agility, so he'll be a lot more capable of generating dangerous chances next season than this year - which says a lot, since he reached 44 goals and 70 points. But Aho is already close and he'll be even better next year at this rate.^
As for the tournament, I think Aho will surpass 20 points for sure. With a fair shot at 25 points, if we go all the way to either final.
Btw, the points record is a massive 34 points, but that was during the hey-day of Soviet Union, when Vladimir Petrov reached that in 1973.
In the past 25 years, the highest tournament score was 20 points by Dany Heatley in 2008.
