Shraga18 -“How do you know he didn’t learn DY?”
That part of my post came from the impression from other posts on different sites. It’s quite possible Choppy is right. I have been out of that part of town for quite some years. When I was there Rabbi Shia Krupenia gave the Daf Yomi in the Yeshiva for as long as I can remember, probably like 20 -25 years or more. If Choppy knows that R. Kotler started giving such a Shiur either first or second -hand knowledge, then he would be able to answer my question.
And even if he is correct, they skipped over Rabbonim who have been giving Daf Yomi Shiurim for years and years and years.
