Compared to the other players, the point guard usually has a special relationship with his coach. The point guard is responsible for running the coach's offensive plays on the field but also must have the knowledge of the coach's overarching game plan necessary to call plays on the fly when needed. For these reasons, a point guard will need to understand the coach's offensive playbook better than anyone else on the team (and will need to be able to execute the coach's instructions as he gives them during the game). In addition, since he's usually in control of the ball at the start of the play, the point guard is tasked with performing certain special duties like calling a time out. Knowing when to do these things requires him to be aware of both his coach's plan and the circumstances of the game (especially late in the game when time outs and other stalling tactics are common). A point guard who can't communicate with his teammates on the court can be a major liability to his team. Point guards should be able to use their voice and body to direct their teammates to set up scoring opportunities, execute plays, and so on. A big part of developing these communication skills is putting in lots of practice as a team so that every member knows what sorts of signals to expect and how each member communicates as a player. The point guard may want to talk to his teammates and agree on a system of signals, code words and so on to keep his team's strategy secret on the court. For instance, if the point guard raises a fist when he's at the top of the key, this can be a signal for the small forward to cut back the three point line and get ready for a pass. Because of your unique position, your other teammates (especially inexperienced ones) may look to you to "set the tone" for your games and practices. A good point guard takes the game seriously, puts in hard work at practice, listens to his coach, and seeks to improve his game outside of practice. Just as importantly, he also encourages his teammates to do the same. By...
