Two people are playing American Football and one of them is trying to stop the other from throwing the ball.
A lineman is trying to tackle the quarterback before he makes the game winning touchdown.
Two people playing football does not imply a lineman is trying to tackle the quarterback before he makes the game winning touchdown.
Just because two people are playing American Football and one of them is trying to stop the other from throwing the ball, doesn't mean a lineman is trying to tackle the quarterback before he makes the game winning touchdown.
Not just lineman will try to tackle other players.
