Well Don Waddell is pretty sure that Coburn will make the squad next year. With Exelby, Kloucek, Kaberle, Tjarnqvist, Sutton, and Majesky I think the chances are pretty slim of Foster being a regular in Atlanta next year.
I would assume he will be on the Chicago-Atlanta shuttle quite a bit though.
Havent seen Foster play all that much but he strikes me as a late bloomer. Raw talent that needs to be refined and he is making some progress. He does have a good upside but may need another year in the A although with guys like him you never know when they will pull it all together.
