His attitude seemed a bit Billy Big to me, a bit 'I've just signed a big sponsorship deal so my time is too precious'. Usain Bolt manages to do one every time he wins overseas personality, and he is the best athlete in the world.
Never let the truth get in the way of a bit of critique! He is currently enjoying some of the very rare family time that his commitments allow him. In the grand scheme of things the SPOTY is a small title not carrying much more sway than the Xfactor runner up. I dont blame him for wanting to have a quiet christmas period.
