People who don't deserve it:
Robinson + Wilkinson: Got to the world cup final after a string of lucky results playing ugly rugby. Then lost to a far superior team. Neither player played that well, and Robinson missed most of the games!
Lewis Hamilton: Did well, but came second. His rookie season so he's got plenty to look forward too. Plus I think hes an idiot for bringing out an autobiography at age 22.
Murray: Has he achieved anything great this year? Rose up the world rankings but didnt really win anything major....his brother would be a better candidate after winning the doubles at wimbledon.
Rose: Same reason as Murray, hasnt really won anything noteworthy to the general public.
Paula Radcliffe: What?? She missed most of the season after having her baby and has won a couple of races since, but still not the runner she once was
Toseland: Perhaps a decent nomination, but a bit of an unknown to the general public.
Ohoruogu: Seriously? A woman who 'missed' drugs tests to win? She should be banned for life.
So that just leaves the two boxers, I personally would go with Calzaghe, Hatton if he beats Mayweather.
Anyway, just my opinion, great British sportsmen seem a bit thin on the ground recently.
