With his goal today, Benson officially has 30 points (11 goals, 19 assists) to close out the season in 71 games. For an 18 year old player, this has by all accounts been a great, if not remarkable season for Benson especially once you take into account some of his bad luck offensively (posts, chances he has generated that were not buried by teammates, etc) and more importantly his invaluable role off the puck on both the forecheck and defensively.
For reference, his 18 year old season is better than every 1st overall forward's 18 year old season (J. Hughes, Laf and Slafkovsky) since Matthews if you don't count Bedard. It's hard to overstate how impressive Benson's season has been for an undersized 18 year old player, let alone one drafted outside of the Top 10.
I think we got a real gem of a player here.
