The Patriots cap space on May 18, 2017 proves they could not have re-signed Jones and Collins? That is way beyond a reach. Of course they could have afforded both players if they felt they were worth the contracts they were asking for. They didn't pay them that money because it was more than the players were worth to them, not because of an economic disadvantage.
They could have afforded Jones and Collins sure. But not Jones, Collins + Hightower, Butler, Ryan, Harmon, Sheard, Long, Bennett, etc
The Patriots were going to lose players due to the cap. It was just a question of which ones.
Let's take the Dwayne Allen trade. The Patriots traded for Allen, so he isn't part of any comp pick offset. They let Martellus Bennett walk, which is part of the comp pick formula. So, they replaced a tight end with another tight end and will get a comp pick for it.
And they lost a pick trading for Allen. Hardly a free lunch.
But really I don't think anyone will argue with your larger point that BB is good at taking advantage of the rules. Just ask Harbaugh
