I have no clue why you would bail the linebacker with 2 high on that first play, and when you are trying to stop a 1st down on 3rd and 3 with under a minute you definitely but 8 in the box and play man knowing it would be foolhardy to risk a pass and stop the clock.
I can excuse the alignment on 2nd and 7, you don't want to sell out just yet and leave the middle of the field open. 8 yard depth is fine for the safeties to adequately run the alleys in run support. I can't defend play 1 or 3rd and 3 at all though, as a coach it makes no sense to me and as a fan it is aggravating.
