how to be a good basketball team captain

There is no significant job of the team captain other than to lead the team, especially in tense situations. Take LeBron James. When his team is down by a few points in the fourth quarter, he doesn't stress out or yell. He encourages his teammates and does not be rude. The team captain is the guy that sets the tone for everyone else. For instance, if the team has been on a losing streak, the team captain will stand up and support the team saying all will get better. The team captain may also lay down the law by giving rules for what the team can and cannot do.

The team captain should encourage the team, be a leader in practices, and set an example.
in my experience, the job of the team captain is to lead in general. wether it is by example during a game by making a big play, or doing something bad and shaking it off, or leading stretches. also if players have a problem on the team, the captain should take an interest to make sure it doesnt affect everyone on the team.
there isn't a certain thing that a team captin has to do but I play softball and here are my tip on being a good captin:

• Always have a positive, up-beat attitude
• always show your teammates that you believe in them and the whole team
• help your teammates improve. (if you help them improve they will respect you)
• respect your teamates
• never get down on someone who makes a mistake, show them what they did wrong and show them the right way of doing it and tell them "its ok you'll get them next time"
• cheer! that's my favorite part of softball bc you can be loud and abnoxious and cheer for your teammates, but down cheer down the other team
• lets say ur playing 1st base if a girl on the other team hits and amazing line drive, when they r on 1st tell them "hey nice rip"( there is nothing wrong with complementing someone, either on your team or the opposing team, for something they did)
• some of the best captins i have had in all my years of sports are not the ones who are the best players or the all-star but the ones who never give up, who help their teammates improve, who are the first to get a cheer going, the first to be out on the feild and stretching, the first to help coaches, teammates and opponents.

Remember sometimes being a leader isn't about how good you are but how you carry yourself and have you treat everyone with the respect they deserve bc a good captin is not only respected by the team but the captin respects everyone on the field as well!

I'm going to add to the above. He seems to be basing his views on captaincy from basketball. In other sports, such as Ice Hockey, captains and assistant captains are supposed to be the only ones allowed to speak to the referees. It's not really enforced but it is a rule.
