Murray basically won the Davis Cup by himself.
In a GOOD year of sport that would make him a contender.
In a pretty poor year it makes only him and Jessica Ennis as possibilities. Murray's stunning performance concluding in late November also will keep it fresh in the mind.
A 'pretty poor' year?
Really?
In 2015, we have regained the Ashes, won the Davis Cup for the first time in 80 years, won numerous swimming and athletics World titles, won our first gymnastics World title, the Formula One World title, had the most succesful ever Women's World Cup and now have the heavyweight Champion of the World.
What for you would constitute a 'good' year!?
