They wouldn’t be standing to the cap in that case.
Hitting that threshold doesn’t put you close to the cap. Look at it this way.
Regardless of the time frame your cap is salary plus a portion of signing bonus. Every contract with a signing bonus is more cash than cap until the last year when it catches up.
Example
5 yr 60 mill contract. With 10 mill sb and salaries of 5,8,10,13,14
After 1 year
Cash spent 15 mill
Cap hit 7
After 2
Cash 23
Cap 17
After 3
Cash 33
Cap 29
After 4
Cash 46
Cap 44
After 5
60/60
Cumulative Cap hits equals salaries plus the part of the bonuses that have been amortized
Cumulative Cash equals salaries plus all amortized AND in amortized bonuses.
If you spend 90% of thr cap number in cash you would be far, far below the cap number.
To date since forever, the difference between cash spent and cap hits is exactly the number of dead money hits that would be absorbed if you cut the whole team (plus the dead money for those cut previously)
