“Completeness” is an overrated concept in football. “Complete” wins don’t count any more than incomplete ones. Incomplete — or flawed or whatever — teams can still win a lot of games, even championships.
But playing what passes for a complete game, and how frequently you’re able to do it, is a reasonably good indicator of where a team is headed. That the Packers were able to put together one of their best full-team performances in a key moment against a divisional opponent seems like a good data point as to exactly what kind of team these young Packers can be.
