Ramczyk has a little work to do on his technique, he is lunging forward a little too much which allows the rusher to beat him. He also flips his hips earlier than he should instead of just continuing to set vertical.
That is stuff that he probably could get away with in college just by being bigger, stronger and faster than most everybody. Luckily that is quite easily corrected in practise. This was a good test for him and I am encouraged.
