WHEN and HOW TO CHOOSE WHETHER TO THROW OR KICK:
The technical skills and physical strength of the goalkeeper have a large impact on this tactical choice.
In modern football, goalkeepers like Reina, De Gea, Handanovic, Neuer and many others are able to throw well beyond the midfield line, which allows them to resolve any situation and choose solutions both near and far, within a 50-metre range. The great advantages of throwing, as opposed to kicking, are:
a) speed of execution
c) chance to change / stop your decision
However, kicking the ball back into play, especially with Brazilian style football (just look at a few images of Keylor Navas) allows even farther solutions to be created and, for this reason, it must be included in training at the same level as the other skills, teaching a tight and accurate trajectory.
