I see your point I just want the players to still play like themselves regardless if they have a skill/badge. Say for example corner three specialist does he stop spotting up for threes if he loses his skill badge even if his tendency to do so has not really changed (Think Battier of last year 3pt% dropped). IMO the tendency should be there the success should drop.
I see tendency as what the player does. Sometimes they do things that are not in their strengths a la Josh Smith chucking mid range jumpers and threes despite not being good there. So I still see the tendency needs to be there to get them to play good or bad. Especially since their are no negative badges.
