With the exit of Matt Stajan and Troy Brouwer, the Calgary Flames have a couple of roster spots up for grabs at the bottom of the rotation. The club’s fourth line was a bad mix of ineffective and expensive last year, prodding GM Brad Treliving to clear out the aging vets and bring in a high skill hopeful in Austin Czarnik.



In addition to Czarnik, Calgary has young incumbents Mark Jankowski, Curtis Lazar, and Garnet Hathaway all vying to stick around. Usually, that would be enough to confidently draw up the depth chart, but this time around the organization has more than a few other kids knocking on the door at the AHL level.



Here’s a look at how the Flame’s minor league depth is shaping up, and the training camp battles that may ensue.
