Pretty true. Last season i had bulgaria nation team member who was playing constantly at starting five as sg but salary was 58k. My mechandise even dropped from 57k to 54-55k, because i sat down my homegrown player of 30k salary because of him. So i assume low salary and weak NT player gives very very few mechandize while starting ur own strong national teams player gives roughly 10-15 percent. depending on national team strenght.
