It's entirely an example. Any way you slice it 30-3-2 is crazy impressive, regardless of league, especially considering Roma hadn't been within 8 points for half the season, so it's not like we've had that constant pressure of a 1-2 point gap at the top. Until Napoli, we were up 11. The fact out players have stayed motivated even with this constant lead is incredibly impressive.
And teams would push the 100 point barrier frequently in lower leagues if it was that easy. Also, how on earth do you know what PSG players feel about the league? Don't be silly.
