There are very few athletes, especially NBA athletes that are well dressed, the ones that dress like 'we' do are never mentioned -thankfully.
Generally, they start getting a clue when they are out of their leagues and become TV commentators, after they are 'guided' by producers to drop the zoot suits.
I can't even think of an athlete that is well dressed, ya, they have 'spensive clothes but no clue how to wear them, just relying on the fact that a designer has done the hard work for them and thinking that price = looking sharp. Beckham has half a clue, but only half.
Best dressed in the sports world are European football (em, soccer) managers....
Among the best dressed managers are Sam Alardyce, manager of Blackburn Rovers in the English Premier League, also, Carlo Ancelotti of AC Milan, Jose Mourinho of Inter Milan, and certainly Roberto Mancini - the former Inter manager before Mourinho took over.
