i would even say that salarie raises different, if you look at new draft with high salary they normally got high rebounding jumpshot ain't so special so that big men more often got higher salaries.
Later in game i could imagine that Inside Defence is more important fpor the salary of the big men then Rebounding for example.
But i think jumshot becomes more important if you compare higher skills with others, but i most be honestly in this categorie i don't watch at so many players ;) But i see some more high skilled shooters then others player as a nt scout but this could happen because jump shot is a popular training.
Handling and Driving i think ain't that much important then the other skills, because they got trained pretty fast but i don't see that the one and one Trainers dominates the game :)
