The Calgary Flames initially got Patrick Sieloff when they traded down in the first round of the 2012 NHL Draft, getting them back a second round pick they had previously lost in an effort to ditch Ales Kotalik's contract. The Flames were excited about him - and there had even been some talk about taking him in the first round, should Mark Jankowski have been taken before the Flames had a chance to pick him.
... Even when you factor in Sieloff's lost season due to staph infection, that still might have been a tad too optimistic on the player's abilities.
