A57 blocks B18 early. A27 blocks B4 early. With this video it's much clearer where the ball is but you have to look at both this one and the earlier one to tell the blocks are early. As far as to whether or not they should get your flag hand "itchy", I don't recall anything in the rule book about A not being allowed to "pancake" block before the ball has gone 10 yards. It says, they CAN'T BLOCK. These blocks are early, should have been called.
