Obviously at 24 it depends on who falls, but out of the realistic options I would love to add any of the following, probably in this order:
1. Ryan Merkley - the talent speaks for itself. Not only is his production historically good, but his shot assist/scoring chance assists are the best in the draft. He should not be available anywhere close to 24, but may be. The criticisms of him are effort and play without the puck. But to me he is a 17 year old kid and you can work on that stuff. You can't teach that skating and hockey IQ though. He is the only truly elite talent that could reasonably be available there.
2. Vitaly Kravtsov - Played in the KHL last year, had ok production but only played limited minutes and exploded in the playoffs once he got to play a little more. And he still only played 13 mins/game in the playoffs (was averaging 9:19 in the regular season). He is a big, fast, highly skilled natural goal scorer.
3. Bode Wilde - The dude has all the talent in the world, but is not a smart hockey player. Think Jake Gardiner. Big, fast, can handle the puck, can shoot, can pass, but he is going to make stupid plays.
4. Akil Thomas - very highly skilled. Put up 1.19 ppg as a 17 year old in the OHL. Plays center. He is not the biggest, or fastest, but he is extremely smart and is a high end playmaker. Kind of reminds me of a 17 year old Kadri without the edge.
5. Nils Lundqvist - Was named top dman in the U20 league over Boqvist. Played 28 games in the SHL. Has comparable production to guys like Brannstrom and the D Aho at the same age. Great skating defenseman, with high hockey IQ and puck skills, and has played at the highest possible levels.
Other names of interest are Calen Addison, Jonatan Berggren, Gregory Denisenko, Rasmus Sandin and Joel Farabee. However, I think the upside is lower there.
