Since the Flames began a rebuild four years ago, forwards Sean Monahan, Johnny Gaudreau and Matthew Tkachuk have gone from prospects into impact players. Center Sam Bennett, the No. 4 pick in the 2014 NHL Draft, is expected to continue toward that in his third full NHL season.
Center Mark Jankowski, the No. 21 pick in the 2012 NHL Draft, played four years for Providence College before scoring 56 points (27 goals, 29 assists) for Stockton of the American Hockey League last season. The 22-year-old is expected to push for a role in training camp.
Right wing Spencer Foo, 23, is another candidate after leaving Union College following his junior season to sign with Calgary as an unrestricted free agent. The expectation is he'll be in the NHL at some point this season.
First-round picks in the 2013 NHL Draft, forwards Emile Poirier (No. 22) and Hunter Shinkaruk (No. 24), each has three full seasons of professional hockey at age 22 and could make the NHL roster.
