Sportswriter Marc Stein was diagnosed with obsessive-compulsive disorder and prescribed a low dose of Risperdal Tuesday after using his weekly ESPN.com power rankings to rate the 'filthiness' of each NBA team. 'Basketball under their fingernails; I wouldn't go near these guys in a million years, okay?' read Stein's entry for the 11th-ranked Pacers, a typical blurb in a list that described the No. 1 Suns as 'pretty clean or less diseased than normal' and the No. 30 Mavericks as 'DIRTY DIRTY DIRTY DIRTY.' An agitated Stein told reporters that he believes teams need to be ranked in many different ways. 'Scoring them from best to worst, or by their 'power,' is one way, but what about organizing them by how dirty they are, their franchise age, or the way they sound or taste? People deserve to know that, although the Lakers are the best team in the league, they are only 23rd in terms of how well-liked they are among their own families. The Detroit Pistons are ranked eighth alphabetically. That's important.' Stein was prescribed an additional dose of D-cycloserin after explaining his plans to wash the entire Northwest Division.
