Robertson could end up being one of the biggest steals of the draft.
Tons of rankings had him as a first rounder:
2019 NHL Entry Draft: Ranked #19 by ISS Hockey
2019 NHL Entry Draft: Ranked #19 by Future Considerations
2019 NHL Entry Draft: Ranked #35 by Hockeyprospect.com
2019 NHL Entry Draft: Ranked #29 by McKeen's Hockey
2019 NHL Entry Draft: Ranked #25 by TSN/McKenzie
2019 NHL Entry Draft: Ranked #26 by NHL Central Scouting
Basically it seems he's a big kid, great skater, effective shut down guy but also good at moving the puck out of his own zone and up the ice effectively and also at jumping into the play.
Could be the type of guy we look back on the draft in 5-6 years and people can't believe he went 49th.
