I'll split the difference here, as is My Way. Patton always told his subordinate commanders that a good plan executed in a timely manner beats a great plan executed too late. If you think DB Coach's plan is good enough "for now," then execute. But bear in mind that there's nothing limiting you from carrying out only one plan at a time. There's a lot in @robx's post -- as @Puppy suggests -- that's worth considering and doing, even as you "give her space" and "let her think."
No, really, there isn't. Robx's post (which I happen to agree with, btw) can be summed up as "Sit her down."
The DB coach's advice can be summed up as "give her space."
