P.J. Carlesimo, who attended Fordham University here in the city and once put the tiny, Staten Island-based Wagner College on the basketball map, was hired yesterday as the new head coach of the Seattle Supersonics. Rather than being known as Wagner’s claim-to-fame, however, Carlesimo is more infamously remembered as the coach that Latrell “I’m-Fucking-Crazy” Sprewell choked during a 1997 practice. His reward? Three years of toiling on the abyss of the Golden State Warriors’ bench, and then eight more years without receiving another coaching opportunity. But finally, after winning three championships as an assistant for the San Antonio Spurs, Carlesimo has been hired to foster the talents of rookie sensation Kevin Durant and save the Supersonics from extinction. It sounds like a tall task, but everything, even the impossible, seems a little peachier after you’ve survived an attempted murder by one of your players.
