Bowman says that the Braves had not made a final decision on which cap to wear when the images of the 'screaming Indian' first leaked. Bowman refers to the original "Screaming Indian" cap as a "potential version" and notes that it was just "one of five proposed designs."
However, saying use of the offensive cap was not finalized would seem like a stretch. The "Screaming Indian" cap is seen in the catalog of New Era, the company that makes the caps. And while many of the teams chose to use secondary or throwback logos on their caps, the Braves are the only team that appear to have abandoned the design in that catalog.
