You obviously don't watch the league. I won't compare it to the Egyptian league as i have never watched any games from there. But the Saudi league is pretty much in the top tier of Asian teams, historically they have been one of the strongest teams in Asia. How is it an ordinary league? Compared to the top European leagues of course its average, but compared to other leagues from its continent, i have to say you are wrong in saying that its ordinary.
Hilal, Ittihad, Shabab and Nasr are all teams that are quite enjoyable to watch.
