I am unsure about even an AA.
I took a quick look at the #1 ranked wrestlers in D2 at each weight. They have very few matches against D1 comp, but even when they do the results are not great. They typically wrestle non-starters and typically do not win. Most of the wins come against guys ranked in the 100 to 300 range on wrestlestat.
The one notable win I found was Ty McGeary, the West Liberty 184, with a 14-4 MD over Clarion's Cameron Pine, who is ranked 33 in D1.
