I always include the 'Saintsweb Man of the Match' in my match reports, the only way to get that is to ask the forum users, if they have been to the game great, it allows them to make a more informed opinion, but opinions will be crafted too from reading match reports and hear'say from mates.
It would also be impossible on here to seperate the match goers from those who couldn't/didn't attend. So while I agree it may be a little less well informed then the official man of the match award, it is a reflection of the forum's opinion and feeling. Therefore it is far from bizare or meaningless.
