Offensive Flow (how well the offense produces assists, avoids turnovers): point guard weighted very heavily, shooting guard weighted medium, small forward weighted medium"
If Point guard skills which are the key part of determining offensive flow then the most important skills for the position seem to go PA, OD, HA as those are the most 'expensive' skills specifically for a PG regarding how wage & cap effects are counted.
Both your guards were the lowest rated of your starters by individual game rating too, and the PG was lowest of all. The PG also only got 2 assists which may have just been a bad night (he did get 7 in the previous game after all!) but also makes me think he doesn't have much passing either, which if so will not be good for his offensive flow.
In short a better PG is the quickest way to get offensive flow up.
