Regarding a midfielder dropping deeper as we build from the back:
I think it's first and foremost a strategy to combat Blackburn's packing midfield and pressing our two central midfielders, like here:

They're reasonably ok with our defenders being on the ball, knowing they're not brilliant with it. Instead, they're determined to target us if we play into midfield. Wilder said he'd warned our players about this:

So Riedewald drops deeper, our centre halves get wider in the hope they're going to get different angles, with better and less risky passing options in front of them:

So, there's some logic behind it, but it's still dependant on things being done right, with tempo, good movement, good accuracy and decision making.
Blackburn have been hard to beat recently, but great sides would still find holes in their defensive setup.
And that is probably a worry, that despite the points tally last season, despite the improvement from the disastrous start, it's difficult to see any real signs that this team is moving towards playing entertaining, modern, high-quality football.
