After sitting on this, I get it
Here’s how I think they see Mazi. He’s big enough to lead a jumbo defense package but athletic enough to develop into a formidable backfield threat. To me, that means on 1st down we might see him and Hankins to keep LBs clean. On 2nd, we would see him and Osa. 3rd and short, he stays in there. 3rd and long you bring in the pass rusher package, which he may someday be good enough to be a part of. I think that translatable utility from down to down is why he has tremendous value.
