The newspaper business is in transition. Fortunately, Glen Taylor knows a thing or two about reinvention. The civic-minded Taylor, who’s evolved from farm boy to printing tycoon to state senator to NBA mogul, is the new owner of the Star Tribune. He bought the paper “half with my head, half with my heart,” but turning around the Strib won’t be a half-hearted effort. Neither is his stewardship of the Timberwolves. One of the league’s more hands-on owners, he is hoping new basketball boss Flip Saunders can right the badly listing ship.
