Boris "au centre"?

According to French sports daily L'Equipe, Coach Vincent Collet is worried about his team's lack of height, since Joakim Noah was declared inapt. He noted that the team's best post-up player is Boris Diaw, who was listed as "center" for the Spurs. Collet did indeed play Boris a few minutes at the 5 during the recent preparation game against Great Britain.

But perhaps someone should explain to Collet that the Spurs' calling Boris their center is just a courtesy to Tim Duncan, who likes to pretend that he's still a power forward... when in fact he has played 5 for years now. So the Spurs list Timmy at 4...and therefore Boris who is in fact their power forward at 5. OK, Vincent?? Got it? Boris is not a center. Play Kevin Seraphin, for pity's sake!
