Not sure if you are asking about traditionally getting some (ala prematch) or all, but if you are talking about the former, Case took 3 of 8 positions (those are the ones that I know of...could be more) via prematch, ie outside of NRMP purview.
There was a new neurology residency program at Valley Hospital in Las Vegas that was outside the NRMP, but they went to the DO match this year. So I guess that doesn't help /
