No, I think you should go back and watch the game footage again. It's like the guy can't tackle cleanly. If you can't see that his second foot is raised and his studs are up on that first tackle, you're not watching. That's illegal, even if you get the ball first, and will sometimes get you a red, let alone a yellow.
And he absolutely mugged that guy on the touchline.
Hard-tackling is fine, but he's a goon.
