You haven't shown anything to prove that point.
Last season the money spent on the DLine was extreme but it was balanced out with Dez, Tyron, Murray, Fred, Leary, T. Williams all being starters on rookie contracts. Half of of your concept is correct in that teams must get significant contributions from players on their rookie contracts in order to manage the salary cap and field a competitive team; however, there is no reason that they have to be on offense or defense.
I have shown that, which is why I keep saying you're not listening.
I've given you a scenario in which a team spends 50% of their non special teams budget on offense and 50% on defense.
In this scenario a team would need to hit on 4-5 draft picks within a 4 year period in order to have a cost effective defense. This is assuming that the other starters on defense took up an average wage from the remainder of the budget.
When you have a team spend even more on offense, it becomes even MORE important to hit on draft picks on defense, which means you generally need to draft even more defensive players.
We can go back to last year and take an actual look at the 2013 split as opposed to just focusing on the spending on the defensive line.
Last year we were 14th in the league in offensive spending, spending 45.2 million dollars on offense. On defense we were ranked 24th in the league spending 36.8 million dollars.
The type of spending we had last year only heightens my point.
When you spend more on the offense, you have to be more successful drafting defensive players, and you also have to be wiser with how you're spending on defense. We didn't do either of these things.
Our money was tied into 30 somethings who were injury prone and in general decline.
