Tucker Kraft is truly irreplaceable, and that statement has been reinforced in both games without him.
The Green Bay Packers knew Luke Musgrave couldn't replace Kraft's production. He's a different player. Kraft wins with his physicality after the catch, whereas Musgrave is more of a vertical threat with his speed and athleticism. But we've seen precious little of that in the two games since Kraft's injury, and it sure looks like the Packers have already given up.
After a disastrous start to the game, Matt LaFleur effectively benched his former second-round pick at halftime. Musgrave played just 19 snaps, fewer than Josh Whyle (20) and John FitzPatrick (35).
