My position on performance is that a higher level of play justifies a higher cap charge, and given that players decline over time it's ridiculous to think an older version of a great player will be more likely to justify a high cap charge than the younger version of the same great player. It's a pretty widely accepted position that you don't pay for age and you don't pay for past performance, but that's essentially what restructuring does. You take a higher charge at an older age, which is when the natural course of a player's career suggests that he won't be as productive.
You don't PAY for age, but a cap charge is not the same as paying the player. You can pay now and get charged later. You're not paying for age, you're just changing when the money you've already paid hits the cap.
As for the percentage of the salary cap a player takes up, I'm not sure why that's even something worth discussing.
Because THAT is what is important as far as building the team, not the specific dollar amount. Think of the cap as being 100.0 NFL currency units each season. The dollars-to-NFLCU "exchange rate" would get smaller each year, but the cap would remain at 100.0 NFLCU. So $5 million dollars might be 3.5 NFLCU this year but only 3.3 NFLCU next year, 3.1 NFLCU the year after than and 2.8 NFLCU the year after that. The same dollar amount becomes a smaller percentage of the cap as the cap goes up.
Fully guaranteed multi-year contracts don't exist, but if such a contract did exist the percentage of cap used would be the same regardless of how it was structured. If a fully guaranteed contract for 4 years paid $50M and the total cap space over those 4 years was $600M, it doesn't matter in what way you structure it in terms of the percentage of cap used over the 4 year period. Percentage-wise, $50M of $600M is the same no matter how you want to split it up.
That's correct ONLY if the cap applies to the four-year period combined, but it does not -- the cap is for only one year at a time. And how a contract is structured affects the percentage of the cap you use each season and the combined percentage of the cap used.
Using your scenario, let's pretend that the caps for that four-year period are $143 million, $147 million, $152 million and $158 million ($600 million total). Now let's look at a flatly structured contract with equal cap charges of $12.5 million per season -- the percentages of the cap would be 8.74, 8.5, 8.22 and 7.91 for a total of 33.38, or an average of 8.34 percent. Suppose you structured the contract so that the cap charges declined each year, from $17 million to $14 million to $11 million to $8 million -- the percentages of the cap would be 11.89, 9.52, 7.24 and 0.51 for a total of 33.71, or an average of 8.43 percent. Same total money, same total cap, but different percentages because of how the contract is structured.
Now let's look at scenarios with increasing cap charges, such as $8 million, $11 million, $14 million and $17 million. The percentages are now 5.59, 7.48, 9.21 and 10.76, for a total of 33.05 and an average of 8.26. With a smaller cap charge to start and greater increases, the percentages become even smaller -- at $4 million, $9 million, $15 million and $22 million, the percentages are now 2.8, 6.12, 9.87 and 13.92 for a total of 32.71 and an average of 8.18.
Just by moving money around, taking bigger cap charges when the cap is higher, you're actually lowering the percentage of your annual cap that you use.
The only way you can say it's foolish is if you believe teams make roster moves entirely independent of the potential dead space a move would make. That's just not true.
I never said teams weren't stupid. They do stupid things all the time.
You'd also have to believe that Brandon Carr would still be on the roster right now if the team were able to free up $8M by cutting him, as they would be had they never restructured his contract.
While $8M could certainly give you the level of play that Carr has provided, the fact that there's next to no cap space created by cutting him means that the team would have to utilize more cap space to replace his level of play than they would just by keeping him. Keeping him is the cheapest option they have right now, and it's entirely because they restructured him. Furthermore, had they not restructured him it's questionable that he is on the roster for 2014 because they could have taken the $6M in dead space it would have created and signed a guy with the $6M in space that cutting him would have freed up.
Dead money is absolutely a deterrent to releasing a player. I'm not sure how anyone could think otherwise.
Again, it's not the restructuring that is the problem -- it's the original contract and/or what the team did with the cap room it saved by restructuring. The team created almost $10.9 million of cap room in 2013 by restructuring Carr. If they kept him in 2014 and paid him an additional $7.5 million in salary ONLY to avoid taking an additional cap hit of $4.651 million, that's completely stupid. And if they're keeping him around this season and will pay him another $8 million ONLY because cutting him now would save less than $600,000, that's also stupid. Who pays an extra $15.5 million to avoid costing themselves less than $4.1 million? If he's not worth his salary, CUT HIM. Don't hang onto him just because it would cause "dead money" -- that only compounds the problem.
If Carr hadn't been restructured at all, the team would have had to have structured other contracts to take smaller hits in 2013 and larger hits in 2014, 2015 and beyond (meaning we'd have less cap room now because other players' cap numbers would be higher); and we wouldn't have been able to carry over as much cap room from 2013 to 2014 and again from 2014 to 2015 without other cap-saving moves (meaning we'd have even less cap room now because even more other players' cap numbers would higher and/or our amount carried over would be less or non-existent). As shown by the examples above, the net effect of restructuring Carr is a slightly lower percentage of the cap being used on him, which is a positive thing, not a negative thing.
As I've said many times, if you're going to pay the player anyway, there's absolutely no reason NOT to structure the contract favorably -- whether that's at the original signing or by restructuring. And if the player isn't worth his salary, you either pay him less (if he'll take it) or get rid of him, don't hang onto him and compound the problem. Anything else is just foolishness.
