A leader should never say I don’t know. The guy is over rated.
I'm pretty sure he didn't mean he didn't know.
It's a dumb question to ask if you are expecting a detailed answer. Typically you get "we have to make some tackles" (duh) or "we need to make some adjustments" (duh) or "we just need to keep playing hard" (duh).
There is no sound bite answer to the question.
