In 2000, longtime sports staple Ron Zappolo moved into the anchor seat at Fox31, helping to establish the credibility of the station's fledgling news operation even as he boosted its profile. Then, last year, he announced that he would be returning to sports reporting, and the knowledge that his days dispensing hard news were dwindling seems to have freed him up. Over the past few months, he's delivered some of the most relaxed, confident and personality-filled performances of his long career — a fine swan song preceding his scheduled April 5 shift to his new/old gig.
