These are the ones that I use:
Felton - RayRay ( this guy needs a nickname in the worst way )
Morrison - Ammo, The Stache
Wallace - Crash ( G-Force is goofy )
Okafor - Mek ( He needs something imposing, like "The Nigerian Assasin"... "Oak" would be nice, bout Charles Oakley owns that one )
Sean May - Last season it was simply "Fatass", but hes showing some game this season so I don't have a decent nickname for him.
Primoz - The Marshmellow
Hermann - Fabio
