NICK FOLIGNO
The long time veteran has already worn the "C" for a different franchise, wears the Alternate Captain's patch for Chicago, and has been just re-signed for 2 more seasons. A big presence on this team and in the community already, seeing Foligno being named captain woulnd't come as a surprise at this point. I'd put him at the second best odds.
What about a longest tenured Blackhawk?
