He obviously thinks about it differently, probably because he’s such a morphology guy, so learning that stuff is at the core of learning the language for him. He has a theory (stated in those lectures or on the blog, can’t recall) that
all Greek verbs are regular. If you learn enough rules, take into account letters that no longer exist in Koine, etc. And he has
a book to prove it. (Not recommending that one for language learning, although it’s interesting.)
