It's been discussed and speculated on ever since the Calgary Flames had their playoff hopes end and saw their draft slot cemented at 15th overall. And recently on Sportsnet 960 The Fan, NHL.com correspondent (and Future Considerations guru) Aaron Vickers noted that the Flames probably will take a long look at forwards Nick Merkley or Travis Konecny if they're available when Calgary comes up to the podium.
I'll go one further: based on the available evidence - historical, anecdotal, statistical and otherwise - I'm thinking that the Flames probably pick one of these two players at 15th overall.
