wrong way
 

Player A goes wrong way and makes a 3 point basket. Does it count for 3 points or 2 points to the other team?

If only that player went the wrong way, then count it for team B.

If "everyone" was gong the wrong way, count it for Team A.

If a player throws the ball into the opponents' basket from outside the arc, it counts two points for the opponents, assuming nothing happened to make the ball dead before the ball goes through the basket, such as the end of the quarter, a foul, etc.
