The Oakland Raiders' new coach and general manager, Al Davis (below), is young, bright, handsome and has recently inherited a small fortune. He has, in fact, everything going for him but a respectable football team. "Gentlemen," Davis told his staff the day he took over, "we have work to do." He was right. The Raiders have only a handful of qualified pros, and the team did not gain much in the draft. Needing a first-rate linebacker to help out Bob Dougherty, Davis traded for Buffalo's Arch Matsos, a fast man who is happiest when demolishing opposing backs. Davis then convinced the New York Jets' fine end, Art Powell, that if he was going to play for a loser, he might as well do it nearer home ( San Diego). Last year Powell led all AFL receivers in yardage gained. The Raiders also have the league's best center in Jim Otto, plus Clen Daniels, who can run with the ball. Oakland will not move much, however, unless Quarterback Tom Flores, a fine passer who sat out last season with a respiratory ailment, comes back strong. Flo-res is second-string to Cotton Davidson at the moment, but he should take over soon. The defensive line has 280-pound Chuck McMurtry, an exceptional tackle, and that is about all. Davis will have to console himself this season with pleasant thoughts of a lavish new stadium Oakland is planning for his team to play in and a couple of games with the Boston Patriots, the team the Raiders beat on the last day of the 1962 season to end a 19-game losing streak.
