I think this looks like what I said in the other thread they may do. A bonus this year and a $5M base salary increase Next year which will eventually be converted to a bonus a year from now. Looks like a good deal for all. You don't screw around with first ballot HOFers who are team leaders and model citizens.
Going by Archer's numbers, It looks like they further reduced his base this year from $1.7M to $1.25M and added a dummy year to allocate the bonus over:
Original 2023 cap hit: $11,040,000 - not original, but before his holdout and subsequent restructure
Salary reduction: <450,000> - from 1.70M to 1.25M
Signing bonus: 1,160,000 - $5.8M/5 years
Revised 2023 cap hit: $11,750,000
Only in the NFL can you give a guy $10.8M and only have it cost you $710K against your cap
