Agreed on zone blocking. However, it is important to hold your ground at a minimum with control of the defender you are blocking.
Note can not infrequently be found getting pushed back--that was my intention. He's mobile, agile and does a meh job right now. Which I am totally fine with from a 2nd year first time starter at lg. The Saffold comparison was just meant as a very clear illustration of how they are completely different players.
I'm not trying to take shots at Note, just calling out what is easily seen on the film. I think he will be a solid player one day. But that day is not now.
