Spurs assistant James Borrego, who appears to have emerged as a serious candidate for Houston’s post, had his scheduled second interview today with team owner Leslie Alexander, Marc Stein of ESPN.com tweets. Houston is also believed to be considering Magic assistant coach Adrian Griffin, Sixers assistant Mike D’Antoni, and Hornets assistant Stephen Silas for its head coaching opening.
