Agree with most of what all other Hull fans have said, Pitts is a good solid player, excellent defender and has a good bit of skill about him at times (watch his pass he gives Horne is our SL game against Salford), for me he doesn't quite do enough in attack and maybe lacks size to become a top class forward. Hull are very strong in the backrow this year.
My thoughts are well documented on Arundel as I am not convinced he is good enough to play for a team who wants to finish in the top 6, though I do agree he has been a bit unlucky with injuries and that hasn't helped him, be interesting to see how he goes for you with a run of games, I hope he proves me wrong.
Not sure if it has been mentioned but Pitts hasn't played in the cup for us, so he will be able to play for you this weekend, Arundel played for us against Salford.
