I would say most experts and even some pros don't see things like this. They "read the D"...which is great, but what happens if your opponent is in your head? I only know these things because I shot NOTHING but the roller for the 3 years I dove into foos. Plus I did 2-5 during that time, so had tons of possessions. Only with a ridiculous amount of time on the 3 row will players begin to see things this way. Just my thoughts. :-)
I find that I am a better blocker from this vid as well. Even though they are better players they often fall for traps when I realize they are trying to read the whole D.
