Team is sorely lacking in outside defence considering how much wages you're paying each week. It's a cheap skill compared to how effective it is in winning games; without sufficient perimeter defence, any offence, even including the inside-based ones, can run wild against you. Good defence at the perimeter will prevent the opposing team from getting the ball inside easily and hence taking lot's of higher percentage shots, whilst simultaneously making their outside shots difficult to make. They say defence wins championships and in this current match engine, it's definitely true.
tl;dr: you need better defensive players.
