I'm sorry I can't get very deep into this, but I'll try and say something...
Again, comparing them salary wise, since this should be a good indication as to how good a player is.
Yep, like you said salary + gameshape + enthusiasm is a pretty good way to summarize game-day strength early in the season.
Looking at salaries, you win at SG, SF, and PF, while Gausons wins at PG. C is a tie. The difference at PF is not as huge as you think. The differences at PG and SG are more important. Overall, you seem to have better starters and would expect to win at home.
How on earth can he have a strong IS rating?
Why not? They played Look inside with good PF/C and their SF (Ovalle) is a big guy.
How can my PF only score 10 out of 28 when he is much better than the other PF and C together
He's not better than them together. You just pay him that much. Anyway, your PF outscored their PF quite nicely.
have look at the stats for Wu Yilong my best player.How can he get a 3 as rating in the game played on the 11th of june
He played at SG where he probably isn't very effective.
You should have played 2-3 zone in this game (I don't know if that was known before the game) and perhaps you should upgrade your PG. Sell your expensive PF, too?
