For week 2, Ant1 has 1 game on their schedule Panionios-PAOK.
ERT has 4, & Sport Plus the other 3.
So 7 teams home games on ERT as Blackhawk mentions above. OSFP and PAOK home games on Sport Plus. Looks like AEK home games on ANT1.
That leaves Asteras Tripoli, PAS Giannina, Larissa, OFI, Levadiakos & Panionios. Not sure if those 6 are assigned to any channel or do ANT1 & Sport Plus pick games as they go along?
