First of all, many guys who go to BMG are not serious learners. For them, it is just the default place to go to avoid having to chas v’shalom do some hishtadlus for parnassah.
Now, the list of other yeshivas for post-E”Y (offhand, and not exclusive):
R’ Asher Weiss (monsey)
Torah vodaas
Mir
Chaim Berlin
Chofetz Chaim (queens)
Zichron Aryeh
Novardok (drillman’s)
Zuckers – marine park
Lander’s
Ohr Hachaim
RIETS/YU
Rodkin’s
Fisher’s
Senter’s West/South Shore
Shor Yoshuv
Waterbury
Derech Chaim (boro park/Kensington area)
Rubenstein’s (Lakewood)
Ateret Torah (Sephardi)
Ner Yisrael
THERE YOU GO! I have just named 20 yeshivas other than Lakewood where guys go after E”Y, and there are plenty of guys in these places I would rather than some guys in Lakewood.
