I think he is great. He is harmless and funny. Is almost like the average fan in the pub. He gets over excited, he sounds like he is on the drink, he can be quite funny and he just enjoys the game.
I really enjoy his unprofessional approach if that makes any sense. I can see what is happening on the screen and his apprach just makes me laugh. So for me he adds something to the coverage. I would rather here him sounding like a drunk on the hill then the docile tones of Peter Sterling and Ray Warren for 80 minutes.
I agree with what someone said above he will need to be careful. I thought it was hilarious that he joined in the "BULLSH!T" chant but alarmed that he would do it so loud and uncaringly.
Good luck to him.
