I think Konecny would be a great pick, even in top 10. Wearing the C for the 67s and for Team Canada at the Under 18's is always a good sign. His game is so well rounded, he's on smaller side but doesn't shy away from physical play, competes at all times, can play in all situations and is so versatile, being able to play centre or the wing, and has played the point on the powerplay.
All that's keeping him outside the top 10 in my opinion is his rough start, 2 goals in 16 games. Dealing with a concussion and playing on such a young team didn't help his cause, but if you watched him play you saw the compete level and knew the stats would come. He's since been one of the best players in the OHL, including at the prospect game, and has 19 goals and 37 points in his last 29 games [plus two goals in the prospects game]. It's no coincidence the 67s have been one of the hottest teams of late since Konecny got going.
Jeff Skinner is a pretty good comparison, both on the smaller side but very strong on the puck, good speed and like to use their wrist shots. I think Skinner is more of a shooter whereas Konecny seems equally likely to pass or shoot. I also think Konecny is more of a complete player at this age, but Skinner's goal scoring ability might've been the best of his age group at the time.
