The state of our rookie list doesn’t matter for Munkara. We can still match bids in the ND after we pass (as we did with Brand in 2020). So we can pass when we’re done, then match a bid if one comes, or just put him on the Cat B list the next day if one doesn’t.
Edit: sorry, I just got what you mean. I think you’re right, yes, if we want the list full (to capacity) and to guarantee we get Munkara while hoping he ends up as a Cat B, we’d need to make sure we had the last live pick in the draft. Which probably wouldn’t be that hard to do, just potentially stupid to watch happen in real time.
