‘New Bills Coach Gregg Williams is taking full advantage of Carroll, a field judge in his seventh NFL season; Bob Wagner, an umpire in his 17th; Doug Rosenbaum, a side judge in his first year; and Tom Johnson, a head linesman in his 20th season. Also in camp is Jim Poole, who worked two Super Bowls during his 21 years as an official and who now trains officials for the league.’
