Travel on Hail Mary

[jump stop]

If you have a travel then explain the rule he violated. He gathered the ball with one foot on the ground(his right foot). If he gathered the ball with one foot on floor he has 3 options:
1) he can remain standing on one foot (which he didn't)
2) He can jump off of this foot and land on 2 feet simultaneously( which he didn't )
3) He can step with other foot(his left foot), thus establishing pivot foot( foot that was first on ground when he caught ball, right foot) , he can then pick up pivot foot (which he did) but he must release ball with pass or shot(which he did).

You have to be able to explain using these rules to the core. These rules are well thought out and genius. Amazing how many people don't understand these. They just go by "it looks like a travel" .
