Hi I have draft picks with 5 potential and 5 star but where does the grade come into it?
The grade is only a more detailed Skillrating, the letter is always related to the Skillrating( A means 5 Ball Skillrating, B four Ball SR, C = 3 ball SR etc.).
The "+" shows it is a good player for his skillrating, and close to the higher level. A "-" means, he just get it into this level but a player with a weaker Skilllevel isn't much weaker. Nothing means he is medium^^
i also have a 4 star palyer with no potential rating who scored 28 points in 24 mins play is he worth a punt at or should i stick to 5 star ratings???
boxscore is just one game, in germany we try to read something out of it in collecting some draft data but the informations you could get out it a pretty low. So i just would use it in comparision, to decide betwen players with similiar informations.
