This has interesting implications for next season. If they re-sign Calder (and I hope they do) and Dats, roster spots for next years team will be getting thin. Quick look at projected line-up with the two mentioned re-signings:
Samuelsson-Kopecky-? (Grigs, Maltby, Free Agent)
Now we can debate the composition of those lines (particularly who would center the fourth), but I have to believe all those spots would be taken, leaving at most one available on the team. This is without considering re-signing Bert, Lang, or Maltby. Frankly if I had a choice, that roster makeup would be ideal; it contains at least three gritty player (Calder, Frazen, and Kopecky), a ton of youth, and some experience.
All in all things look good for the Winged Wheel.
