Interesting to look at this site which tries to aggregate and establish consensus rankings based on multiple sources:
http://www.mynhldraft.com/2015-draft...nsus-rankings/
Using this analysis, if we divide into tiers (say 10+ points between tiers), we see the following:
1. McDavid, Eichel
2. Strome, Marner, Hanifin
3. Provorov
4. Werenski, Crouse, Barzal, Rantanen
5. Zacha, Connor
6. Meier, Merkley
7. Svechnikov, Konecky
8. White, Chabot, Eriksson Ek, Roy
9. Zboril, Boeser, Sprong, Harkins, DeBrusk, Kylington, Samsonov, Bittner, Guryanov, Bracco
If tiered this way and drafted in order, the Flames would have Svechnikov and Konecky available at 15 to choose in the top tier available. Svechnikov (LW, 6'1" 180) would have the advantage in size, Konecky (C, 5'10", 172) in position.
