I can't think of what you would mean by 'down block', if by some chance you are referring to boxing, it could be 下のブロック /shi ta no bu ro-kku/.
If you mean it litterally, you just push the football down and then you'll get the hang of doing it.
It means when a hole block of land comes down a hill
defence in football is stopping the goals that the other teams strikers try to score so they have to block them and make sure they dont score.
