To elaborate more, the shorter a player is, the faster he trains in guard skills, like Jump Shot and Outside Defense. A 6'11 guy would train substantially slower than a 6'0 player, so try to get a shorter guy when training guards. Vice versa for big men, taller is better for training. A 7'0 trains substantially faster than a 6'0 guy in inside skills, such as Rbd and Shot Blocking. Heights of Small Fowards usually fluctuate by manager.
