In terms of cash, the deal went from $50m down to $25m and now up to $32m. Some of that goes to FA, 20% of the new deal and an unknown amount of the earlier deals (which was largely the trigger for the clubs’ revolt).
The salary cap dropped from $3.2m in 2019/20 to $2.1m in 2020/21. Wouldn’t surprise me if it comes back a bit (e.g. $2.4m) but I couldn’t see it going much higher than that.
