I guess in your specific example Player B could be *slightly* better. Since playing at SF & using base offense is a rare case where all skills might be equally important. (I need to give it some more thought first). There won't be that huge a difference in performance though. It' not going to win or lose a game for you.
But were your example about PG and playing look inside... Player A is looking like the better choice. Same for a similar example at center (replace PA & OD with Rebounding & ID)
No, of course not. But since Player's A two skills at Prominent take bigger share of his DMI than rest of his skills, we can say that compared to Player B, Player's A relative skills look like this:
6, 6
8, 6
6, 8
6, 6
6, 6
But player A's game shape isn't horrible (it's respectable), so it's more that
player B would be getting a performance boost rather than player A getting a penalty. Perhaps player B now has all skills close to 8? While player A has has all 7s except the 10s in PA & OD.
