Off the top of my head i think its because we've played st kilda a few times on monday nights.2014 R8 St Kilda
Its not about DAYS, its about the opponent. Fridays are a harder opponent than Mondays. Thats the way the AFL run things for ratings
EDIT: We've played St. Kilda 5 times from our last 6 monday night games. For a 3-2 record.
We also beat Geelong, Brisbane and Richmond for the other 3 games.
