For many years, the three captains in Chicago were Jonathan Toews (C), Duncan Keith (A), and Patrick Sharp (A). Once Sharp left to play for the Dallas Stars, the Chicago Blackhawks promoted Brent Seabrook to be their second alternate captain.
Patrick Kane is the next man up when it comes to alternate captains in Chicago. Kane normally wears the “A” on his sweater if Toews, Keith, or Seabrook don’t play that game. We’ve seen a lot of that during the last few seasons, with most of it coming this past season.
