You need to match up, but it's not entirely about size,.. The traditional Purdue in the paint post player is a dinosaur position.
You're the only one talking about traditional (offensively) post players.
What you say isn't wrong. But others seem to be able to make a distinction.
And for the record, traditional post players still remain some in college. And definitely a ton of guys that should be traditional post players, if coaches weren't all using ball-screen offenses.
Also for the record, Purdue didn't use their bigs for post-ups near as much as they have in the past.
Also, expect to see much more posting up from Iowa next season, to help generate offense with the loss of Stirtz. Probably not camp on the block post-ups as much as cleared side back-downs. Al and Jirak will get them, especially as they a great passers. And a group of skilled forwards that can punish mismatches
