Dear Ujm,
You are incorrect. Most of Rav Aharon’s talmidim (This only means those that were Rosh Yeshivos.) advocated for English programs. Some avoided it. But it seems like they were on the fence about it. I am only certain about one talmid, (Including non RY.) that was open in his opposition to English. Maybe there were a few others. But the concesus coming out of Lakewood always was that your yeshiva and it’s bachurim would be more matzliach with a full high school curriculum. But in Lakewood itself, the opposite became true.
