Thanks for advice.
There are many players that were scouted once. What does give a Star Rating without knowing other parameters? When guy has a 5 stars-balls can it indicate that he is a good choice, while having a good statistics?
I got 1 scouting of my 32 players and second scouting from 10 guys. From the 10 guys selected is one SG, A+, 4 stars-balls potential, but unfortunately 19 and has a very bad stats.
So, probably I would select some guys from the first scouting as a first choice.
Like I said statistic is very random, we can't even now in what kind of match he played. Of course 5 stars can indicate good choice, for me everyone lower than 5 star rating goes at the bottom of my list but 5 star rating doesn't indicated that he has higher potential.
Now if you like risking you can choose one scouted 5-star rating rookies as your first choice, but I think that SG is pretty good. I once took SF with same information 5star-grading, A+ 4star potential and he turned out to be very multiskilled.
