to talk to people
Use the telephone.
so you can talk to people. fast.
We use telephones to talk with. These days, people use cellphones .
You dial a phone number and hit talk or send.
You could but it would be very risky. I have seen games where both quarterbacks were injured and the team had to use a running back to finish the game (Washington/Philadelphia, 1990 ... the 'body bag' game). I can't say that I know every player on every NFL roster but I can't imagine there is a team that carries less than three quarterbacks on their 53 man roster.
It's a convenient way to talk to people without having to see them personally.
To talk to a friend who lives far from your house you can use a phone or a computer (Skype, Facebook, etc.).

A telephone is a device you can use to talk to people all around the world. It is a great tool. I love using it!!!!
