Can't judge Rizzi based on program he didn't build

Why on earth would they not practice at full speed? Serious question. Someone help me make sense of it because it sounds insane to me.
Maybe because they had to spend so much time teaching the offense to all of the backups. No sense in having them run the wrong plays at full speed.

The teams are also very limited on contact practices, I forget the total but it is less than one per week (and once you've used them, you're out).
