Well put.
Trump has missed a great opportunity to truly come across as a leader. His pressers should be comprised of
(1) him with an opening statement of inspiration and hope
(2) turning over the entire technical aspect of the questioning to his experts
(3) him with a closing statement of inspiration and hope.
The hallmark of an effective executive is the ability to guide the ship a 1000 miles away ..... Not navigate every white cap and eddy.
His bickering with the lame stream media is especially disconcerning. Don't get in the mud with them.
If I had it my way, these briefings would only be held when there was something particularly important to announce and even then, I would rather VP Pence take charge of them since Trump presumably named him to head the federal response. But since Trump wants to be there all the time, what you suggest is reasonable.
Trump is good at delivering a prepared speech. Talking off the cuff, however, is not good for him. At his rallies he can say whatever he wants and his audience of supporters will applaud every word. But these briefings are supposed to be for all of us, not just for his supporters -- to educate, inform and encourage us all in a time of crisis. I don't think that's what's happening here. What we are getting is Trump, the candidate for re-election and the master entertainer with his constant battles with the press. Maybe this persona works for his supporters, but it does nothing for the rest of us.
And when it comes time to vote in November (or whenever the general election is held), I suspect some people are going to remember these "briefings" and hold them against him. Democrats, if they are smart, will replay Trump's words in campaign ads, reminding voters on a daily basis of these supposed "briefings" and Trump's appalling performance in them. Trump needs independents, undecideds and maybe some unhappy Democrats on his side to win re-election. Effective campaign advertising will put them off even if the economy improves.
