GREEN BAY, Wis. — Micah Hyde, the Green Bay Packers’ jack-of-all-trades in the secondary, is assuming another new role this season — playoff playmaker. He is listed as a safety on the Packers roster, but really plays more of a slot cornerback role, at least when he’s not needed to fill in on the outside against receivers. Whatever Hyde is called upon to do, the fourth-year defensive back out of Iowa has found a way to make an impact.
