Murray is 5000 points behind Nole. He is not as consistent as Djokovic. Some miracle would need to happen for Murray to become #1, don't think it's gonna happen, 0.00001%.
see what I said ?
Nadal is even further and has all of his points to "defend" in the first part of the year contrary to Murray,
but they don't fear Murray at all : 0.00001% whereas they still fear Nadal !
is it reasonable ? no, imo, Murray is quite as dangerous as Nadal reasonably, at least nearly as dangerous, but memories from the past tend to be too much printed in people's minds who think that everything has been definitevely said.
