I wasn't sold on him in his first couple of seasons, but he seems to have really come on. That said, his finishing is really good, but the rest of his game isn't anywhere near the standard of guys like Hall or Briscoe yet. He is another to add a growing list of exciting wingers though.
People do get a little overexcited about him diving in at the corner though. It's smart finishing, because if you get your feet off the floor it makes it really hard for the defender to do anything. But the skill involved isn't as great as some would have you believe. Hell I've seen Liam Colbon score one this year.
The scrum half at Hull is Harry Tyson Wilson. I don't like to overhype youngsters before they've even broke into the first team, but he's a good as anyone I've seen at his age in this country.
