JetMetFan wroteSince "path" isn't defined in the rule book the next best thing is the dictionary. One of the definitions is "the area in front of someone...that is moving." So while A1's direction in my example is backwards, his/her path would still be towards the goal if they're still facing B1/the basket.
Stop the clip at the 2 second mark. B1 is not in A1's path when A1 starts his drive diagnoally.
