Nom, spoken like a true Lubavitcher. Lots of gedolim said he wasn’t big in learning, including the Brisker rov.
The Lubavitcher rebbe was not a rosh yeshiva who wrote chidushim or gave gemara shiurim from which we can see his level of learning. He gave sichos in chasidishe Torah (supposedly), which is a lot easier. Being able to darshen does not make you a gadol batorah
Is it any wonder that in chabad, they extol their rebbes memory, supposed miracles, and fiery drashos, farbrebgens, his alleged behind the scenes work on behalf of Russian jewry, etc…
Never heard a good pshat in a rashba from him. Maybe he did write such things, but I’ve never heard of it.
