So it has already been announced that the following new players will wear these numbers:
TJ Galiardi - #39
David Jones - #54
Corban Knight - #10
Shane O'Brien - #55
Plus Horak has switched to #21, and Monahan has #23 obviously.
But it looks like Bouma is being given a real number now too, #17.
Certainly reinforces the idea that the Flames management think highly of Lance and feel he has a well defined role on this team going forward.
