Player outside the line

[BIG O]

RM,

Would you call it a violation if A1 has the ball at the top of the key, with a group of players in the low box, then A2 runs the base, easily a foot out of bounds, then returns to catch a pass from A1 on the other side of the box? A2 clearly run out to go around the group of players to get open..... This is the rule....

All of my violations this year have been on the endline, just like the above situation.
