There is none to make and he knows it. By saying the coaching staff is considering changes but isn't ready to make them is Rhodes' way of saying there's nothing that can be done to this lineup. If practical lineup changes were possible, they've been done already. There isn't any magic waiting on the Packers bench. This isn't the NBA, where a guy can jump off the pine for a week, get hot and ignite a winning streak.
Football is the ultimate team game, where continuity and rhythm are essential.
If Rhodes were to make a couple of changes, it would do no good. The Packers aren't lacking in need of one specific area. They simply aren't clicking in several areas. No particular position can be pointed as the primary problem. Antuan Edwards plays a lot in the dime packages.
