I don't think it's bum rush ala Pool ..
I do think if you look at the better Spurs performances of the last 2-3 years, it's been when we up the tempo. It isn't all about running or over-pressing, it's about moving the ball quickly and early, when we do that and leverage the speed of our FBs we can be very difficult to play against. Poch knows this, it's why Mason/Bentaleb got their start, they recycled the ball quicker, it's why even if you look at the practice drills on social media today, it's quick passing in tight situations.
It does seem the combination of pressing without exposing yourself, holding possession, recovering the ball quickly, passing quickly and leveraging the FBs requires the team to have a rhythm, and we seem to take some time to find that at the beginning of a season.
