Unstoppable corner routes

Any tips?  I’ve watched Zan over the years and he usually has good tips, but even dropping the curl flats to 30, playing match, cover 4, etc., there are just some players who can still exploit it.  I’ve noticed the normal y off close (I think) and some NE gun formation seem to be the formations that bust up the sidelines and get the corners open most.  I suspect, for whatever reason, certain formations just exploit the programming more than others, just like inversely, there are some defensive formations that share the same personnel and should share the same run fits, but due to the formation, some just bag up the run better than others.  Any feedback is appreciated

Switch stick.

This year corners have been harder to complete because of the switch stick.

Appreciate your reply, bro.  What is the switch stick?  The play?
