The defending-champion Packers are 5-0 after Sunday night's comeback win over the Falcons, but linebacker Clay Matthews says the team hasn't yet hit it's stride. "It's nice to know that we're not playing our best ball, yet we're getting better and at the same time we're still winning," Matthews said, "so we're 5-0, got a chance to go 6-0 and play better ball next week heading in to Week 7 and just continue to develop and progress as a football team. "That's what's encouraging."
