"Offensive Flow (how well the offense produces assists, avoids turnovers): point guard weighted very heavily, shooting guard weighted medium, small forward weighted medium."
That is just how the in game team ratings work.
High passing SF - PF - C can have a huge impact on the game especially if your playing against weak OD players.
multi-demintional players can have a huge impact on the game and how they impacted the game will not be indicated in the team ratings.
Use the in game team ratings as a guide but dont put 100% faith in them.
SB can be huge if you have a weaker RB team than your opponent. It can prevent those offense RB turning into easy second chance points.
What i am going to do is build bigs with lower RB and higher SB and that should give me a very affordable player.
