Washington Wizards guard Gilbert Arenas said Wednesday he studies referees' tendencies "the way some people study the players." He said nothing stood out about Donaghy, who called seven Wizards games last season, all during the regular season.

Arenas did, however, express concern about the league's image. "At the end of the day, I hope fans understand that this is one person," Arenas said. "I don't want people thinking that all of the refs are cheating, just like I don't want them thinking that because one player gets in trouble, all players are getting into trouble."
