I've been calling for Micah to go back to being a true hybrid player for a while now, but right now you have to just wait. Honestly we don't even know who the DC is going to be in 2024, and I'm not sure if this is a black and white decision on Micah. I think the worst thing you can do is make him 100% DE or 100% LB.
The Cowboys have a very interesting group of DL, depending on who returns of course. They have a lot of tweener body types that they could get creative with their alignments if they wanted to. Honestly I wouldn't hate at all if they ran a mix of 3 and 4 man fronts and have Parsons lining up all over the field. He could literally be MLB, 3-4 style OLB, and DE all in the same game.
