How can we have the cake and eat it too?
Salary cap is no problem - $10M/yr annual rise until 2020 - unprecedented.
Massive cap manipulation is possible as a result.
For example, TSmith's and TFred contracts are built for annual restructuring for creating cap space.
Here is a simple example for free agent X with a 50M 5 year contract and $9M signing bonus:
Year ------Year 1---------------Year 2-------------Year 3-----------Year 4----------Year 5
Base -------$1M ----------------$10M--------------$10M-----------$10M-----------$10M
Bonus------$2M ----------------$2M--------------$2M-------------$2M-------------$2M
Cap hit----$3M-----------------$12M-------------$12M-----------$12M-----------$12M
In year 2, to open up cap space, you restructure the contract with a $8M restructure bonus and while reducing year 2 salary to $2M:
Year -----Year 2-----------Year 3-----------Year 4----------Year 5
Base -----$2M------------$10M------------$10M-----------$10M
Bonus----$2M -------------$2M-------------$2M------------$2M
Restru---$2M--------------$2M-------------$2M------------$2M
Cap hit---$6M------------$14M------------$14M-----------$14M
You can say $6M is pretty big for a restructured contract. The reason it is $6M is that I did not cut the base salary to $1M because the math is more cumbersome. It could easily be $5M. Cap experts can probably do better also, but this is my little attempt.
This type of contract is typical, and can be used to resign Mo or replacement FA CB, TWill, DT Mcclain, Church, Wilcox and even Leary. The year 1 cap hit for these could be in the range of: Mo/replacement ($3M), TWill ($2M), Mcclain ($2M), Church ($1.5M), Wilcox ($1.5M) and Leary ($2M), totaling $12M. The year 2 cap hit for these could be in the range of: Mo/replacement ($5M), TWill ($3.5M), Mcclain ($3.5M), Church ($2M), Wilcox ($2M) an Leary ($3.5M), totaling $17.5M.
You can also argue that as you keep restructuring, the $ keep rising and sooner or later it will blow up. That is where the $10M/yr annual cap rise comes in, as well as Romo/Witten contracts coming off the books.
