“…However, observing the variables that load the factors, we find that the variables of factor four (lost balls) can only appear in situations of defensive transition, while the variables of factor five (picking up free balls) can only appear in situations of offensive transition. Similarly, Ruan, Ge, Gómez, Shen, Gong, and Cui [ 50 ] give factors 6 and 8 the same name (defense of goalkeepers) even though, as the authors report, different teams have higher values in each of them. Moreover, in the study by Gómez, Mitrotasios, Armatas and Lago-Peñas [ 8 ], factor four was named counter-attack despite the fact that one of the loaded variables is lost balls, which cannot result in a counter-attack.…”
