I need to watch DL more, but I think I've also seen them using Clark at NT more and letting Reed at the 3 tech more, which is how I always thought it should be.
Clark absolutely can play the 3 tech, but his best and natural fit is the NT role.... and I think the reverse is also true for Reed at the 3 tech.
Wyatt is clearly a 3 tech, plus don't ever put him at NT...
