Not sure if this is posted (can't tell with this board!) but BSN has a SN article on the pick with quotes: https://www.sportsnet.ca/baseball/mlb/2018-mlb-draft-live-blog-commentary-reaction-analysis-blue-jays-picks/
Highlights:
"The Blue Jays have been on Groshans for more than a year and liked how he fared with a wood bat against some high-level competition. “A combination of contact, of power, of plate discipline," Sanders said. "He’s got a great feel and approach at the box. He’s able to drive the ball to all fields and we’re certainly confident his offensive ability will translate to the next level.”
"As for Groshans' defence, the Blue Jays will give him a shot to play shortstop in pro ball. “Jordan is a shortstop and we certainly plan to give him opportunities to play there,” Sanders said. At the same time, it's not like he's necessarily a slam-dunk defender at short. Seems to me they picked him for his bat and if he has to move to third, so be it."
