Do you think Stamkos is the best leader on this team?
That's a good question. What makes a good leader? Age and experience? He's the 7th oldest player on the team (crazy right?) - behind McElhinney, Coburn, Maroon, Shattenkirk, McDonagh and Killorn. He has the 2nd most NHL career games (754) behind only Coburn (932) on the team. The only player on the team that has won the Cup before is Maroon.
Is it performance and leading by example? Stamkos is known for having worked with Gary Roberts. His program is known to be one of the most demanding. Not only the workouts but it also requires to stay on a strict diet. Stamkos has won several trophies and awards in his career (2x Rocket, 6x All Star among others). He's battled through several injuries that could've ended his career (broken tibia, blood clot) and yet he finished last season at a career high 98 points. Playoffs though? Eh. His team has gone deep several times but not exactly because of him. In over 70 playoff games he has a 0.76 PPG average, nowhere near close to his 1.03 PPG pace during the reg.
Personality? Hard to judge. He's obviously grown comfortable with the media and giving interviews, appearing at charity events and so on. He's well-spoken, friendly, calm. Not exactly the type of guy you'd imagine giving a booming motivational speech in the locker room.
But who are the alternatives? Hedman is even more calm, almost shy in interviews. Not a man of many words. Kucherov even more so plus he has a history of snapping in the most selfish ways possible when the going gets tough. Not exactly what you'd want out of your leaders or captain, right?
This has also been a concern for a while now with this team since the departures of Vinny and Marty. The current players, they are all kinda shy and kinda calm. You rarely see them communicate on the bench when things are going wrong. No discussion, no advice, no cheering on the crew on the ice. Often times it's just about sending a positive message but nobody does it. They rather sulk in quiet and stare into space until their next shift. "Hopefully the game ends soon."
Yzerman, the longest serving captain in NHL history with three Stanley Cup wins under his belt, was calm and collected too. But he was arguably the most complete player on his team who just lead by example, limping on one leg through OT and scoring the deciding goal against St. Louis for example. Nobody would question him and his word. He also had a good leadership supporting cast in Shanahan, Lidstrom, Larionov et al.
Honestly, I don't have an answer to your question. I think there are many better leaders - but on other teams. Though, I'm not so sure that there's anybody better than Stamkos on the Lightning.
