it think such specialities should bring always an disadvantage with it, since it get introduced late and the previous player generation oviously don't have it. Like late bloomer training slower at the beginning, clutch player playing a bit worse in the first 3 quarters etc.
Something like ballhog you can get by mixing the skills, which is at least for me enough.
naming then after NBA players, is imho misunderstanding* and could cause trouble with the rights of the players. So i would forget about that.
* with hearing melo, i think on bad defense and clutchness first. with Aj Green i don't get a picture and jordan is also famous for lot more.
