Maybe it will be a blessing in disquise. Maybe if Lawrence's start to the season is delayed, Charlton will finally step up. I've always believed Charlton is more of a LDE than RDE, so his progress is hampered by playing behind Lawrence. When they drafted Charlton, I immediately said his long-term upside is similar to Tony Tolbert - who also played LDE opposite Charles Haley. And I've got to believe the Cowboys drafted Charlton as a potential replacement for Lawrence, while they hoped Gregory would be their long-term RDE. Gregory is still the long-term hope at RDE - although that hope is fading. And Robert Quinn is a very good choice to play RDE now while Gregory is out on yet another suspension. Also, the Cowboys could always choose to negotiate a longer term deal with Quinn next year, who is still only 28 years old.
While Lawrence is better than both Charlton or Crawford, either one of those players can adequately play the LDE position, as long as you get a top pass rusher at RDE. And you can shift Jaylon Smith to Strong side LB and blitz him off the edge on the left side to create more pressure. The Cowboys now have options at RDE - Quinn and Gregory. And who knows if Armstrong will develop. But I'm not overly concerned about Lawrence missing a couple of games, and allowing Charlton to develop.
