If Bozak and Komarov are still around, I can see both wearing a letter. I wouldn't be shocked to see one or both traded though...
If we sign Stamkos, I think he'll be more than capable of coming into the room and fitting right in with the M.O. that Babcock and company have created. I also think they'll commit leadership roles to guys with long-term contracts.
A full offseason with the media, and a training camp flush with renewed expectations should be enough to justify his appointment as Captain. Surround him with other young veteran leaders like Rielly/Kadri and I think you've got an interesting group.
I agree that Kadri may need to try to improve his reputation with league officials, but I like the competitiveness he's shown, and his dedication to the rebuild.
At present, I can see this:
A - Bozak
A - Komarov
A - Rielly
If Stammer is brought in:
C - Stamkos
A - Bozak
A - Rielly
By 2017 I could see:
C - Stamkos
A - Kadri
A - Rielly
And eventually you've got to believe that both Marner and Matthews will take on leadership roles with the club! Often there are quality leaders in the room that don't wear a letter too - because of minimal on-ice roles, or the fact that many young players have to prove themselves a little bit.
Regardless of who ends up wearing letters for us this season, I'm very excited to see what kind of group these guys become!
