Tool of the Week: Danny Ainge, Serena Williams or Daniel Nava?

Here are this week's nominees for the NH Bragg Tool of the Week.

Danny Ainge and the Celtics for letting the Doc Rivers situation become a mess, and during it all having the dancer auditions as the lead story on their website.

Serena Williams for her childish insults directed at Maria Sharapova saying she won't be invited to the cool parties.

Red Sox Outfielder Daniel Nava for dropping a flyball against Detroit and not knowing what constitutes a catch.
