The 2017 NHL Combine wrapped up the testing phase today, and the recorded heights and weights are out there for you to study. No one seems to have noted down the wingspans.
This source has most of the prospects who were at the combine listed, so if you need to know that Nico Hischier is half an inch shorter than Nolan Patrick and 20 pounds lighter, you can look it up there.
For our purposes, I’ve added the heights and weights to our table of likely draft prospects, and also updated the Future Considerations and McKeen’s rankings to reflect their June lists.
