A midrange jumper generally is somewhere from the paint to the perimeter. If you take a 22 foot shot you're on the perimeter, but if you're in the high post, you aren't at the perimeter. Boozer is excellent at the high post, and it's a good bet he's going to be starting there a lot, also because the Spurs will fight to keep him out of the low block. Boozer has a number of very good moves from either place, but I saw Duncan catch Steve Nash from behind at least four times during the Suns series, so Boozer might be wise not to try to rely on his quickness.
