Jones came from the Patriots which were primarily running a 34 then... nothing changed going to Arizona. Lawrence has put alot of time getting his weight from 251 when drafted to around the 270 he's at now. Don't really see him flexible enough to drop into coverage and his 4.8 combine speed at 251 probably hasn't gotten any better!
and they will design and diversify how they would use in Dlaw as a 3-4 OLB.
At 265 range, he's just not big enough to be a 3-4 end either. So like Chandler Jones, he would have to play the 3-4 OLB role.
And have to hope it works and Nolan can best scheme for him.
The better coaches adapt and scheme to what their better players can do.
Kevin Greene wasn't depended upon to drop into coverage as a 3-4 OLB either. and if anything they drop back into occasional zone coverages, not take on a lot of man coverage.
But we'll have to wait to see Nolan's base defense and scheme concept is made of.
