It seems the stat lines can be a bit misleading. Since it is only one game's stats, the results can be skewed a bit, as I have read. Perhaps the SG in your example played a really bad team or poor defender, or had a great game compared to avg? Or perhaps not, he always plays like that. Someone else in your conf may have the same guy scouted, and the stats they see are for a different game, where he shot 25% with 5 TO. The reverse may be true of the Centers in your example. Not saying it is completely random or anything, but it isnt hard evidence either.
In your above example, I would seriously look at that SG.....if he had high potential too. It's an informed crap shoot :)
