Cant' and won't disagree with a word you said: pretty accurate. DLaw is NOT worth a huge deal and Jones did get burnt down the stretch quite a bit, especially in the playoffs. Problem with DLaw is that Randy and DIrv are gone: so he has leverage he ordinarily wouldn't have.
Charles Haley was great at Dallas. However, would he have been great without guys like Lett, Maryland, etc.? There's no way to answer that of course, barring going back and replaying the seasons without those guys. But it seems too many here (
not saying you) who seem to expect Lawrence to put up monster numbers all by himself, which few IF ANY defensive ends in the league can do. People routinely trash Crawford, et al as no good or not as good as their salary, then say "Lawrence disappeared" for stretches. If he's "the guy" for pass rushing, teams will concentrate on stopping or slowing him and if the other guys don't step up then it's not Lawrence's fault.
And saying let's trade him for a 4th round pick and expect that 4th rounder to out-shine Lawrence is pretty far fetched.
It's not a perfect world, Cowboys may pony up the big bucks and it pays off big, or they may pony up big bucks and it bites them in the butt, or they let him go and a draftee or Armstrong or Taco comes in and shines.
We just need to hope the first scenario plays out, because this team needs a better pass rush if it's going to be successful (SB or NFC championship), whether they get an Earl or whatever elsewhere...
