That % absolutely is a benefit. Particularly if you are talking pay as you go vs. 40 mill or so of money pushed back. Pay as you go and you've used 31% of your yearly cap. Push back and it is 29%. You might call that chump change -- but it amounts to nearly 3 mill of extra money in cap space to spend.
People call this "paying on the credit card" but it is actually the opposite. The expense goes DOWN proportionally when you push money back
It looks like you're simply just taking $40M/$130 (and $40M/$140M) to come to a difference of $3M overall, based on the percentage difference multiplied by this year's cap? Just trying to get on the same page before I go on.
If you were relieving yourself of $40M in cap space, you'd be restructuring $50M overall to cover the 1/5th of the money that is moved from base salaries to prorated dollars for the current year. I'm sure you're aware but just went with $40M all at once to simplify the scenario.
So it would look like this:
2014: Cap Total - $40M
2015: Cap Total + $10M
2016: Cap Total + $10M
2017: Cap Total + $10M
2018: Cap Total + $10M
If you convert the $10M for each year into current dollars based based on what amount $10M is out of the cap total, you'd get:
2014: ($140M/$130M) x $10M = $10.76M
Basically, $10M on a $130M cap is equal to to $10.76M on a $140M cap so you come out $760K up when it's said and done.
$150M cap = $11.53M
$160M cap = $12.30M
$170M cap = $13.07M
That covers the proration time so the sum of the differences between the 4 future years and the amount prorated to each years is your "extra".
For 2014 to 2017, that would equal $47.69M, which is $7.69M in "extra" cap money. Average of $1.9M per year "extra" money to spend. Over the 4 year span, that $7.69M works out to just about 1.24% "extra" cap space on the cap total of $620M from 2014 to 2017.
Miles Austin's cap numbers over the 2014 to 2015 combine to about $40.6M. You cut him right now and take the full cap hit and you're still opening up $32M in cap space to spend over the 4 year span. If the team cuts Parnell, Costa and Durant and replaces them with rookies they'll have made half as much spending space by not having them on the roster for just this year. If you're going for extra spending space, it seems like solid roster management would be a much better route to go. I doubt there's a team in the league that couldn't free up more cap dollars by cutting a guy who barely even plays and replacing him with a rookie without a hit in production. You couldn't even meet half of Nate Livings contract with that "extra" cap space.
Also, isn't that extra only there for the single year? Beyond year 1 in which you created the initial room, any sort of bonus based on percentage of cap space would seem to be partially making up for a larger reduction in cap space in those future years? Even if you could get a similar amount of "extra" in year 2, you've added $10M in cap charges to that year so the net for future years would be a reduced cap total relative to the league ceiling, wouldn't it?
It's just doesn't seem significant enough to be a real plus for restructuring. It's especially doesn't seem significant enough when you don't even get the added benefit of signing players to improve your team, which is where Dallas has been for the past few years because their restructuring is out of necessity, not choice. Honestly, other than Carr has Dallas made a signing that anyone thought would really make a significant difference over the past few years? Waters maybe, for a single season?
