I'm a big Yacob fan, but although his 2nd booking was harsh tonight, he really doesn't help himself with his two-footed jumps into tackles. He's getting a reputation for it and refs are looking for it. Tonight he didn't really make contact and Lawrenson I think called it right, but when you look at the replay he definitely starts to make a two-footed jump.
He is always at high risk of a sending off because of the role he plays, but he can reduce those risks by eradicating the two-footed jump.
