They've gotten great quality in the back half of the first round/first part of second round over the last few years...Hintz (49), Oettinger (26), Robertson (39), Harley (18), Johnson (23), Stankoven (47)...Not to mention getting Heiskanen at 3.
Obviously, they've refined their drafting process, but even still there's a lot of luck involved. To get 3-30+ goal scorers, a top goalie, a #2 defenseman, and a potential 60+ point player in Stankoven after 18 -- No one can convince me that there isn't luck involved.
