There's no greater example than Jonathan Toews, who is at top of mind these days as we hope for the best.
The captain played every shift as if it mattered, because all shifts matter. He did not cheat the backcheck, the forecheck or the empty net. He played only to win and set the example for all to follow.
When you saw him return to the bench after a shift, or stand and face reporters after game, it was clear that he was spent, that he had given all he had, with only one goal in mind.
There is so much respect for the man that no one wore a "C" on the Blackhawks' sweater this year. See, leadership isn't a letter stitched on cloth, points on a stat sheet or title given by management.
You know it when you see it -- and you know it when you don't.
There have been others over the last decade of Hawks hockey who fit that bill, the likes of Marian Hossa, Andrew Ladd, Andrew Shaw, Brent Seabrook, Niklas Hjalmarsson and Duncan Keith are just a few that come immediately to mind.
