From the beginning, Channel 31's 9 p.m. newscast had a weak link: former Broncos placekicker David Treadwell, who did a fine job gabbing about sports on the radio, but looked wooden and awkward in the glare of TV lights. The arrival of Eric Goodman, who most recently worked at a Fox Sports Net outlet in Chicago, has given the show a significant boost. He's a fast-talking, quick-witted sports nut from the old school; he's even got a facial mole, like a lot of broadcasters did in the years before TV news became so homogenized. He gives recitations of scores and stats the sort of boot Treadwell managed on the field, but not on the air. Hiring Goodman was a good move.
