When the Rav was sick he divided his shiurim among his son RCS, his brother RAS and his son in law RAL etc. Decades before when Dr BR was sick the great RYHR offered to give his shiurim and sponsor all of YU until he got well. So many Rabbonim and Geonim were with him. Like Harav Fuhrer from Holyoke ( a Volishiner) and Harav Zelmanovich from Williamsburg who was a talmid of the Avnei Nezer. (The Polish Reb Chaim). The first thing the Rov did was establish a day school in Boston. ( First out of town DS). As did RMS established YRMS so the Rav would have talmidim. All agreed that America needs Torah at all times.
