NFL referees throw their hats because they have already thrown their flags and the play has not stopped yet.
To signify a fumble.
It means that there was a penalty on the previous play The flag is the thing the referees throw out
The referees have to control the game and players, and decide when the ball is a free kick, penalty, throw in and a corner.
To show that there has been a change of possession.
If you throw it right, the football will spiral everytime.
You throw a football like you would a baseball.
Cause when you go to games the water the players drink they throw it at the grass
The same way that males throw an (American?) football.
In a game of flag football, any receiver is eligible to be thrown to after the ball is hiked. Regular football games have more strict rules, but in flag football, you can throw to anyone.
I say it this way: "I like to throw and catch a football."
