Not very much until you do not develop it in a site about that guy.
Also, the problem with celebrity domain names is that they will not be high valued after a while, especially in sports, when these people will retire.
However that is a good OVT score, I say you better develop it, work on SEO, and you will monetize the eventual traffic, you will be more rewarded than by trying to sell the domain name.
Name is reg fee but potential is big.
