Everyone trying to come up with a "team of the season" is missing the big picture here. Wake up. Your team of the season is route 1. It doesn't matter who you put in your top XI Southern United, you'll still lose each game resoundingly with your incomprehensible style of play. Half of your team selections are based on your political connections affiliated with the teams, whilst the few indisputable players that you have to put in (but would rather not if given the opportunity) make up only 20% of players not from your preferred club. E.g. making a 70% team of Mosgiel (or any other club here for that matter) players your team of the year is obnoxious and deluded to say the least.
Southern would win more games by playing to their strengths and everyone buying into the style or play (defensively solid and getting the ball forward as quickly as possible) than trying to play aesthetically pleasing, patient passing football.
The reason numerous players tend to be picked from the better performing teams is the mentality and style of play these clubs have.
