It's hard to imagine an AF so unsure about NGAD, after years of funding, research, and studies would have coherent concept of operations for CCAs.If you're trying to respond to a developing attack 500 miles away you're going to need a teleporter to get the CCA's there at the same time as NGAD. Defense doesn't always give one the luxury of planning every detail that offense does.
From what Frank Kendall said, each manned fighter may have up to 5 CCA wingmen. NGAD would have a greater reach and the ability process information with its sensors and could feed CCAs with a fused picture of the battlespace. But what what other roles does it play? There has to be some type of control, and ability to reposition, prioritize, and engage or not engage targets. Do drone wingmen perform a similar role to manned wingmen?
