steals also depend on the opponent's players. If his PGs are good ball handlers and passers,your PG won't steal the ball from them that often. Normally any player can steal from anyone, but in BB my idea is that positions are mostly put against each other (didn't check this for sure though) so if your SG gets a lot of steals, it is possible the opponent's SG had bad handling.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
