You throw a football like you would a baseball.
The same way that males throw an (American?) football.

The same way you throw a football normally, just with more power.
I say it this way: "I like to throw and catch a football."
Tim Tebow can throw a football between 65 and 70 yards

it depends on how hard you throw
