I remember seeing Thurman Munson when he came up to play for the Yankees in late 1969, and having the feeling from the way he carried himself that he was going to be a very good major leaguer. I have much the same feeling about Gary Sanchez. Teams will no doubt catch on to him and he won't continue on the same tear that he's been on, but he should be a very good hitter and he'll only get better as a receiver (and he's already better than most major league catchers that I see). He gives the impression of someone who's been in the bigs for a few years, and not for less than 20 games.
