That's all fine and dandy but I don't think Lawrence really wants to hear Garrett talk about salary cap responsibility. I mean in the end, the Cowboys are offering him a really large contract that's going to have salary cap implications down the road anyway, so the HC telling him they need to be more responsible with the cap in this contract when they are likely only quibbling over a few million per year isn't going to sit well.
You want real salary cap responsibility? Don't sign him at all. Trade him and look for cheaper options at DE (which I am coming around to that idea if you can get Quinn and then consider Ansah for less).
This is nothing but Garrett being a public mouthpiece for Jerry. It's probably not going to sit well with Lawrence and his camp.
