They aren't saying the river will change course due to opening of the Morganza. They are saying if the structures fail, the river could change course. The natural flow of the river would be the atchafalaya now if not for levees and control structures. In 1900, 5% of the river went down the atchafalaya. By 1950, 30% was going that way. Without human intervention, atchafalaya would have become the Mississippi sometime in the last 30-40 years.

That's ORCS, not Morganza. If the Morganza structure fails, still almost no chance that the river changes course. Additionally, opening the Morganza spillway prevents it from failing due to overtopping.
Earlier in the thread, a dude asked what the negatives were to opening the Morganza spillway. Several people responded that the biggest negative was the potential for a river avulsion, which is false. Hence, my comment.
