Yes, there is a hidden "physical" skill.It's not strictly good or bad -- you just might want some players who are physical, and some who aren't.You probably don't want a team of all very physical players. However, it's probably the easiest thing to get from looking at the boxscore page -- if they average 4+ fouls per game, they're probably very physical players.
Is there anything positive in aggressive players?
Is there anything positive in aggressive players?most certainly.a good shooter from te field with bad FT skill will get less points if your physical player fouls him a few times...
