No, it's the fact you got the opening game of the year against your arch rivals and also the biggest holiday match of the year.
Let's see what you get this year without those matches.
What 2 home games, with attendances of 35,952 and 40,752 had that big an influence on home crows in 12 gmaes? I don't think so. Let's look at the Roosters home attenmdances in 2013:
Round 1 v Souths - 35,952.
Round 3 v Brisbane - 13,047.
Round 4 v Parramatta - 18,014.
Round 6 v Canterbury - 22,552.
Round 7 v St George-Illawarra - 40,752.
Round 8 v Penrith - 11,176.
Round 11 v Melbourne - 19,164.
Round 14 v New Zealand - 11,040.
Round 16 v Manly - 16,246.
Round 19 v Cronulla - 13,706.
Round 22 v Canberra - 13,223.
Round 25 v Gold Coast - 17,542.
If you want to talk about low attendances, at least those beat the 5,288 that turned up at Leichhardt Oval in Round 16 to watch the Tigers v Melbourne, or in the same round the 6,271 who turned up at Penrith to watch Penrith v St George.Those 2 games had the lowest crowds in 2013.
