What is an assist?

[dv8r]

alright, ill just make a random example
what if the keeper throws it to the LB (that should count as a pass), LB jizzes pass everyone and scores (lets say it took 30 seconds). does the keeper get an assist?
RL example, i didnt watch the game so enlighten me. a keeper threw it to ronaldinho. ronaldinho jiizzes pass people and shoots from outside the box (that took around 10 seconds right?). did the keeper get an assist?

Technically he should get the assist because he set up the goal. It doesn't matter how far the ball travelled, if the keeper made the pass that directly lead to the goal then it is classed as an assist. GKs have gotten assists before for long throws where the receiving player ended up scoring.
