Rules Question on strange D1 Ending (Video)

[Kend]

I have a rules question involving a D1 men's game.

An offensive player (O1) is running along the baseline with a screen being set on the right side of the lane. He steps on the baseline as he goes past the screen, then cuts to the wing area. He takes 7 steps while completely inbounds and establishes position 15 feet from the nearest boundary. While he has been running, his PG has been dribbling the ball. After O1 has established position 15 feet inbounds, the PG passes the ball to him. Whistle blows for O1 receiving a pass at this point. Is this correct? The rule and case law that may apply are vague and poorly written.

Second part. IF this a technical violation, would you call it with 11 seconds left in a tie game? For perspective, O1 was not looking to shoot when he caught the ball and he gained no advantage stepping on the line.

Third part (which I left out earlier to simplify): O2 stepped on the baseline initially because he was jostled by a defender. Does that affect the ruling?


Thanks for any help on understanding this.
