Well I wanted Klefbom with out 19th pick, so I might be a bit biased
Klefbom is a good skater for his size but still could work on that part of his game. He has a good first pass and a good shot as well. He is strong and is willing to go into the corners,
good hockey sense and is a good a leader.
He can still work on his defensive play though. Not saying it's bad but it can be better IMO. I honestly believe he has the upside to become a number 1 defencemen, he has all the tools to do so. However, I expect him to be more of a number 2-3 defencemen. I hope he reaches his potential though.
