Surprisingly, when the Senators took Filip Chalpik in the second round, I'd actually heard of him. Damien Cox had him going as Ottawa's first-round pick in his mock draft for Sportsnet. He was also the 18th-ranked North American skater for NHL Central Scouting. Bob McKenzie had him going later, 39th overall, but still earlier than the pick the Sens got him at. Hockey's Future had him 35th overall, and McKeen's had him 40th overall. (HF and McKeen's not linked due to pay wall.)
First, some stats:
Centre with Charlottetown (QMJHL) - 6'1", 196 lbs
Regular season: 33 G, 42 A in 64 GP
Playoffs: 1 G, 8 A in 9GP
Those stats were good enough to finish third among QMJHL rookies in points, and first in goals.
