I think BB- don't explain this changes enough, tommorow my National team play match against Espana, and I want to know all changes, who was changed...
Starting after the all-star break, teams with better offensive flow (as usual, compared to the defense) will find themselves able to create shot opportunities more frequently than teams with poor offensive flow, and therefore will tend to get a better shot.
so I would say you don't have to worry about how offensive flow is going to affect you yet.
